ZOE-M8 - Data Sheet
1 Functional description
1.1 Overview
The ZOE-M8G and ZOE-M8Q are u-blox’s super small, highly integrated GNSS SiP (System in
Package) modules based on the high performing u-blox M8 concurrent positioning engine. The ultra-
miniature form factor integrates a complete GNSS receiver including SAW filter, LNA and TCXO. ZOE-
M8G is the 1.8 V variant, and ZOE-M8Q is the 3 V variant.
ZOE-M8 SiPs are mainly targeted for applications that require a small size without compromising
performance. For RF optimization, the ZOE-M8 SiPs integrate a front-end SAW filter and an
additional front-end LNA for increased jamming immunity and easier antenna integration. A passive
antenna can be used to provide a highly integrated system solution with minimal eBOM.
Incorporating ZOE-M8 into customer designs is simple and straightforward, thanks to the fully
integrated design, single voltage supply, low power consumption, simple interface and sophisticated
interference suppression that ensure maximum performance even in GNSS-hostile environments.
With its dual-frequency RF front-end, the ZOE-M8 GNSS SiPs are able to utilize concurrent reception
of up to three GNSS systems (GPS / Galileo together with BeiDou or GLONASS). In addition, the ZOE-
M8 SiPs provide SQI interface for optional external Flash, allowing future firmware upgrades and
improved A-GNSS performance.
Thanks to u-blox’s advanced algorithms and complete GNSS solution, the ZOE-M8 SiPs meet even
the most stringent requirements in versatile industrial and consumer applications, such as UAVs,
vehicles and assets tracking. It also supports message integrity protection, anti-jamming, and anti-
spoofing, providing reliable positioning in difficult environmental conditions as well as in security
attack scenarios.
The ZOE-M8 SiPs can be easily integrated in manufacturing thanks to the advanced S-LGA (Soldered
Land Grid Array) packaging technology, which enables easier and more reliable soldering processes
compared to a normal LGA (Land Grid Array) package.
The ZOE-M8 SiPs are fully tested and qualified according to the JESD47 / ISO 16750 standard.

1.5 Supported GNSS constellations
ZOE-M8 GNSS SiPs are concurrent GNSS receivers which can receive and track multiple GNSS
systems: GPS, Galileo, GLONASS and BeiDou. Owing to the dual-frequency RF front-end architecture,
either GLONASS or BeiDou can be processed concurrently with GPS and Galileo signals, thereby
providing reception of three GNSS systems. By default, the M8 receivers are configured for
concurrent GPS and GLONASS, including SBAS and QZSS reception. If power consumption is a key
factor, then the receiver should be configured for a single GNSS operation using GPS, Galileo,
GLONASS or BeiDou and disabling QZSS and SBAS. The ZOE-M8 SiPs can be configured to receive
any single GNSS constellation or any one combination from the set of permissible combinations
shown below.

The augmentation systems: SBAS and QZSS can be enabled only if GPS operation is configured.
Galileo is not enabled as the default configuration.
1.5.1 GPS
The ZOE-M8 positioning SiPs are designed to receive and track the L1C/A signals provided at
1575.42 MHz by the Global Positioning System.
UBX-16008094 - R08
Production Information
Contents
Page 7 of 31
ZOE-M8 - Data Sheet
1.5.2 GLONASS
The ZOE-M8 SiPs can receive and process the GLONASS satellite system as an alternative to the US-
based Global Positioning System (GPS). The u-blox ZOE-M8 positioning SiPs are designed to receive
and track the L1OF signals that GLONASS provides at 1602 MHz + k*562.5 kHz, where k is the
satellite’s frequency channel number (k = -7, ..., 5, 6). The ability to receive and track GLONASS L1OF
satellite signals allows the design of GLONASS receivers where required by regulations.
To take advantage of GPS and GLONASS, dedicated hardware preparation must be made during the
design-in phase. See the ZOE-M8 Hardware Integration Manual [1] for u-blox design
recommendations.
1.5.3 BeiDou
The ZOE-M8 SiPs can receive and process the B1I signals that are broadcast at 1561.098 MHz from
the BeiDou Navigation Satellite System. The ability to receive and track BeiDou signals in conjunction
with another constellation results in higher coverage, improved reliability and better accuracy.
Currently, BeiDou is not fully operational globally and provides Chinese regional coverage only. Global
coverage is scheduled for 2020.
1.5.4 Galileo
The ZOE-M8 SiPs can receive and track the E1-B/C signals centered on the GPS L1 frequency band.
GPS and Galileo signals can be processed concurrently together with either BeiDou or GLONASS
signals, which enhances coverage, reliability and accuracy. The SAR return link message (RLM)
parameters for both short and long versions are decoded by the receiver and made available to users
via UBX proprietary messages.
☞
Galileo has been implemented according to ICD release 1.3 (December 2016). Since the Galileo
satellite system has only recently reached Initial Services (IS) and has not yet reached Full
Operational Capability (FOC), changes to the Galileo signal specification (OS SIS ICD) remain
theoretically possible. u-blox therefore recommends the use of Flash memory in designs that
utilize Galileo signals, in order to allow for a firmware update in the unlikely event of a change to
the Galileo signal specification (OS SIS ICD).
☞
Galileo reception is by default disabled, but can be enabled by sending a configuration message
(UBX-CFG-GNSS) to the receiver. See the u-blox 8 / u-blox M8 Receiver Description Including
Protocol Specification [2] for more information.
1.6 Assisted GNSS (A-GNSS)
Supply of GNSS receiver assistance information, such as ephemeris, almanac, rough user position
and time, will reduce the time to first fix significantly and improve acquisition sensitivity. All u-blox
M8030 based products support the u-blox AssistNow Online and AssistNow Offline A-GNSS services,
support AssistNow Autonomous, and are OMA SUPL compliant.
1.6.1 AssistNow™ Online
With AssistNow Online, an Internet connected host downloads assistance data from the u-blox
AssistNow Online service to the receiver at system start-up. The Multi-GNSS Assistance (MGA)
service is an HTTP protocol based network operator independent service.
Supplying assistance information, such as ephemeris, almanac, a rough last position and time, can
reduce the time to first fix significantly and improve acquisition sensitivity.
☞
The AssistNow Online service provides data for GPS, GLONASS, BeiDou, Galileo and QZSS

ZOE-M8 - Data Sheet
1.6.2 AssistNow™ Offline
With the AssistNow Offline service, users can download long-term orbit data over the Internet at their
convenience. The orbit data can be stored in the memory of the application processor or alternatively
external SQI flash memory (if available). The function requires no connectivity at system start-up,
enabling a position fix within seconds, even when no network is available. AssistNow Offline offers
augmentation for up to 35 days.
☞
AssistNow Offline service provides data for GPS and GLONASS only, BeiDou and Galileo are not
currently supported
1.6.3 AssistNow™ Autonomous
AssistNow Autonomous provides aiding information without the need for a host or external network
connection. Based on previous broadcast satellite ephemeris data downloaded to and stored by the
GNSS receiver, AssistNow Autonomous automatically generates accurate predictions of satellite
orbital data (“AssistNow Autonomous data”) that is usable for future GNSS position fixes. The
concept capitalizes on the periodic nature of GNSS satellites; by capturing strategic ephemeris data
at specific times of the day.
u-blox’s AssistNow Autonomous benefits are:
•
•
•
Faster fix in situations where GNSS satellite signals are weak
No connectivity required
Compatible with AssistNow Online (can work stand-alone, or in tandem with AssistNow Online
service)
•
No integration effort; calculations are done in the background, transparent to the user.
☞
The ZOE-M8 SiPs utilizing external Flash can predict accurate satellite ephemeris for up to six
days after initial reception. The ROM based ZOE-M8 can use only GPS satellites with a prediction
time of up to three days.
☞
For more information on A-GNSS, see the u-blox 8 / u-blox M8 Receiver Description Including
Protocol Specification [2].
1.7 Augmentation systems
1.7.1 Satellite-Based Augmentation System (SBAS)
The u-blox ZOE-M8 SiPs support reception of SBAS broadcast signals. These systems supplement
GNSS data with additional regional or wide area GPS augmentation data. The system broadcasts
range correction and integrity information via satellite which can be used by GNSS receivers to
improve resulting precision. SBAS satellites can be used as additional satellites for ranging
(navigation), further enhancing availability. The following SBAS types are supported: GAGAN, WAAS,
EGNOS and MSAS.
☞
For more details see the u-blox 8 / u-blox M8 Receiver Description Including Protocol Specification
[2].
1.7.2 QZSS
The Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system that transmits
additional GPS L1C/A signals for the Pacific region covering Japan and Australia. The ZOE-M8 SiPs
are able to receive and track these signals concurrently with GPS signals, resulting in better
availability especially under challenging signal conditions, e.g. in urban canyons. The L1-SAIF signal
provided by QZSS can be enabled for reception via a GNSS configuration message.

1.7.3 IMES
The Japanese Indoor Messaging System (IMES) system is used for indoor position reporting using
low-power transmitters which broadcast a GPS–like signal. The ZOE-M8 SiPs can be configured to
receive and demodulate the signal to provide an in-door location estimate.
☞
This service is authorized and available only in Japan.
IMES reception is disabled by default
☞
1.7.4 Differential GPS (D-GPS)
u-blox ZOE-M8 SiPs support Differential-GPS (D-GPS) data according to RTCM specification 10402.3
[4]: "RECOMMENDED STANDARDS FOR DIFFERENTIAL GNSS". The use of Differential-GPS data
improves GPS position accuracy. The RTCM implementation supports the following RTCM 2.3

For more details, see the u-blox 8 / u-blox M8 Receiver Description Including Protocol Specification
[2].
1.8 Broadcast navigation data and satellite signal
measurements
The ZOE-M8 SiPs can output all the GNSS broadcast data upon reception from tracked satellites.
This includes all the supported GNSS signals plus the augmentation services SBAS, QZSS and IMES.
The receiver also makes the tracked satellite signal information available, i.e. raw code phase and
Doppler measurements, in a form aligned to the Radio Resource LCS Protocol (RRLP) [5]. For more
details, see the u-blox 8 / u-blox M8 Receiver Description Including Protocol Specification [2].
1.9 Odometer
The odometer function provides information on travelled ground distance (in meters) based on the
position and Doppler-based velocity output from the navigation solution. For each computed distance
since the last odometer reset, the odometer estimates a 1-sigma accuracy value. The total
cumulative ground distance is maintained and saved in the BBR memory.
☞
The odometer feature is disabled by default. For more details, see the u-blox 8 / u-blox M8 Receiver
Description Including Protocol Specification [2].
1.10 Data logging
A ZOE-M8 SiP can be used in data logging applications with an external SQI flash. The data logging
feature enables continuous storage of position, velocity and time information to the SQI flash memory
(at least 16 Mbit). The information can be downloaded from the receiver later for further analysis or
for conversion to a mapping tool.

For more information, see the u-blox 8 / u-blox M8 Receiver Description Including Protocol
Specification [2].
1.11 Geofencing
ZOE-M8 SiPs support up to four circular geofencing areas defined on the Earth’s surface using a 2D
model. Geofencing is active when at least one geofence is defined; the current status can be found by
polling the receiver. A GPIO pin can be used to indicate status, e.g. to wake up a host on activation.
1.12 Message integrity protection
ZOE-M8 SiPs provide a function to detect third party interference with the UBX message stream sent
from receiver to host. The security mechanism “signs” nominated messages via a subsequent UBX
message. This message signature is then compared with one generated by the host to determine if
the message data has been altered. The signature algorithm seed can use one fixed secret ID-key set
by eFuse in production and a dynamic ID-key set by the host, enabling users to detect “man-in-the-
middle” style attacks.
1.13 Spoofing detection
Spoofing is a process whereby a malicious third party tries to control the reported position via a fake
GNSS broadcast signal. This may result in the form of reporting incorrect position, velocity or time.
To combat against this, the ZOE-M8 SiPs include spoofing detection measures to alert the host when
signals appear to be suspicious. The receiver combines a number of checks on the received signals
looking for inconsistencies across several parameters.
☞
This feature does not guarantee to detect all spoofing attacks.
1.14 EXTINT: External interrupt
EXTINT is an external interrupt pin with fixed input voltage thresholds with respect to VCC. It can be
used for control of the receiver or for aiding.
For more information about how to implement and configure these features, see the u-blox 8 / u-blox
M8 Receiver Description including Protocol Specification [2] and the ZOE-M8 Hardware Integration
Manual [1].
1.1.1 Pin control
The pin control feature allows overriding the automatic active/inactive cycle of power save mode. The
state of the receiver can be controlled through the EXTINT pin.
The receiver can also be forced OFF using EXTINT when power save mode is not active.
1.1.2 Aiding
The EXTINT pin can be used to supply time or frequency aiding data to the receiver.
For time aiding, the time can be supplied using hardware time synchronization where an accurate time
pulse is connected to the EXTINT pin.
Frequency aiding can be implemented by connecting a periodic rectangular signal with a frequency up
to 500 kHz and arbitrary duty cycle (low/high phase duration must not be shorter than 50 ns) to the
EXTINT pin, and providing the applied frequency value to the receiver using UBX messages.

1.15 TIMEPULSE
A configurable time pulse signal is available with u-blox ZOE-M8 SiPs.
The TIMEPULSE output generates pulse trains synchronized with GPS or UTC time grid with intervals
configurable over a wide frequency range. Thus it may be used as a low frequency time
synchronization pulse or as a high frequency reference signal.
By default the time pulse signal is configured to 1 pulse per second. For more information see the u-

Table 4: Available Protocols
All protocols are available on UART, DDC (I2C compliant) and SPI. For the specifications of the various
protocols, see the u-blox 8 / u-blox M8 Receiver Description Including Protocol Specification [2].
1.17 Interfaces
A number of interfaces are provided either for data communication or memory access. The embedded
firmware uses these interfaces according to their respective protocol specifications.
1.17.1 UART
The ZOE-M8 SiPs make use of a UART interface, which can be used for communication to a host. It
supports configurable baud rates. For supported transfer rates, see the u-blox 8 / u-blox M8 Receiver
Description Including Protocol Specification [2].
☞
Designs must allow access to the UART and the SAFEBOOT_N pin for future service, updates and
reconfiguration.
1.17.2 SPI
The SPI interface is designed to allow communication to a host CPU. The interface can be operated in
slave mode only. The maximum transfer rate using SPI is 125 kB/s and the maximum SPI clock
frequency is 5.5 MHz. Note that SPI is not available in the default configuration, because its pins are
shared with the UART and DDC interfaces. The SPI interface can be enabled by connecting D_SEL to
ground (see section 1.17.5). In this case the DDC interface for data communication is no longer
available.
1.17.3 Display Data Channel (DDC)
An I2C compliant DDC interface is available for communication with an external host CPU or u-blox
cellular module. The interface can be operated in slave mode only. The DDC protocol and electrical
interface are fully compatible with Fast-Mode of the I2C industry standard. Since the maximum SCL
clock frequency is 400 kHz, thus the maximum transfer rate is 400 kb/s.
The DDC interface is I2C Fast Mode compliant. For timing parameters, consult the I2C standard.
☞
The maximum bit rate is 400 kb/s. The interface stretches the clock when slowed down while
serving interrupts, so real bit rates may be slightly lower.

1.17.4 Serial Quad Interface (SQI)
An SQI is available in ZOE-M8 SiPs for connecting with an optional external flash memory. The flash
memory is required for firmware updates and for data logging. In addition, it can be used to store
configurations and to save AssistNow Offline and AssistNow Autonomous data.
☞
For more information, see the ZOE-M8 Hardware Integration Manual [1].
1.17.5 Interface selection (D_SEL)
At startup the D_SEL pin determines which data interfaces are used for communication. If D_SEL is
set to logical “1” or is not connected, UART and DDC become available. If D_SEL is set to logical “0”,
i.e. connected to GND, the ZOE-M8 SiPs can communicate to a host via SPI.

1.18 Configurable Input Output pins
Configuration settings can be modified for several Input/Output pins with either UBX configuration
messages or pin selection. This flexible configuration options allow the receivers to be optimally
configured for specific applications requirements. The modified settings remain either permanent or
effective until power-down or reset depending on the case. Customers can activate or remap the
following pins on ZOE-M8 SiPs:
•
•
•
Selection of DDC, UART TX/RX pins interface or SPI using D_SEL pin. See section 1.17.5.
Selection of external interrupt pins. See section 1.14.
Configuration of Timepulse. See section 1.15.
☞
For more information, see the ZOE-M8 Hardware Integration Manual [1].
1.19 Safe Boot Mode
If Pin C4 (SAFEBOOT_N) is set to logical “0” at startup, the ZOE-M8 receiver enters Safe Boot Mode.
In this mode, the receiver does not calculate positioning data, but is in a defined state that allows such
actions as programming the flash memory in production, or recovering a corrupted flash memory.
☞
For more information about Safe Boot Mode, see the ZOE-M8 Hardware Integration Manual [1].
1.20 System reset
The ZOE-M8 SiPs provide a RESET_N pin to reset the system and Real-Time Clock (RTC). The
RESET_N pin should be only used in critical situations to recover the system.
1.21 Clock generation
1.21.1 Oscillator
Both ZOE-M8 SiP variants have a TCXO. The TCXO allows accelerated weak signal acquisition,
enabling faster start and reacquisition times.

1.21.2 Real-Time Clock (RTC)
The use of the RTC Clock may be optionally used to maintain time in the event of power failure at VCC.
The RTC is required for hot start, warm start, AssistNow Autonomous, AssistNow Offline and some
Power Save Mode operations.
The use of the RTC is optional. The time information can be generated in one of these ways:
•
•
by connecting to an external RTC crystal (for lower battery current – default mode)
by sharing another RTC oscillator used within the application (for lowest system costs and
smallest size)
If the main supply voltage fails and a battery is connected to V_BCKP, parts of the baseband section
switch off, but the RTC still runs, providing a timing reference for the receiver. This operating mode is
called Hardware Backup Mode, which enables all relevant data to be saved in the backup RAM to later
allow a hot or warm start.
☞
See Table 12 for details of RTC voltage requirements when using an optional RTC.
☞
For more information about crystal operation and configuration, see the ZOE-M8 Hardware
Integration Manual [1].
☞
If neither backup RAM nor RTC are used, the backup battery is not needed and V_BCKP should be
connected to VCC.
1.22 Power management
u-blox ZOE-M8 SiPs offer a power-optimized architecture with built-in autonomous power saving
functions to minimize power consumption at any given time. Furthermore, the receiver can be used in
two operating modes: Continuous mode for best performance or Power Save Mode for optimized
power consumption.
1.22.1 DC/DC converter (optional and only on ZOE-M8Q)
ZOE-M8Q has an option to make use of a high-efficient, built-in DC/DC converter to allow low power
consumption. To use the DC/DC converter, a capacitor and an inductor must be added to connect
V_DCDC_OUT to V_CORE.
If the built-in DC/DC converter is not used, VCC, V_DCDC_OUT and V_CORE need to be shorted.
☞
For more information, see the ZOE-M8 Hardware Integration Manual [1].
1.22.2 Operating modes
u-blox ZOE-M8 SiPs can be configured to run in either continuous mode or a choice of power save
mode configurations. A template of power mode settings can be used to easily select typical power
mode setups to cover the majority of users’ requirements.
For specific power saving applications the user has the option to fully configure via the power save
mode configuration. More information see the section 1.22.2.2.
The ZOE-M8 SiP power mode setup offers a choice of continuous operation and preset power save
mode configurations.

1.22.2.1 Continuous mode
Continuous mode uses the acquisition engine at full performance resulting in the shortest possible
TTFF and the highest sensitivity. It searches for all possible satellites until the Almanac is completely
downloaded. The receiver then switches to the tracking engine to lower power consumption.
Thus, a lower tracking current consumption level will be achieved when:
•
•
•
A valid GNSS position is obtained
The entire Almanac has been downloaded
The Ephemeris for each satellite in view is valid
1.22.2.2 Power save mode
For specific power saving applications outside the typical preset power mode setups, users can
configure a tailored power save mode.
Power save mode provides two dedicated methods, ON/OFF and cyclic tracking, which reduce average
current consumption in different ways to match the needs of the specific application. These
operations can be set by using a specific UBX message.
☞
For ON/OFF power save operation, an RTC signal is required.
☞
☞
Position accuracy in power save mode is degraded compared to continuous mode.

For more information regarding MSL, see the u-blox Package Information Guide [3].
☞
6.4 Reflow soldering
Reflow profiles are to be selected according u-blox recommendations (see the ZOE-M8 Hardware
Integration Manual [1] for additional information).
6.5 ESD handling precautions
⚠
ZOE-M8 positioning SiPs contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Observe precautions for handling! Failure to observe these precautions
can result in severe damage to the GNSS receiver!
GNSS receivers are Electrostatic Sensitive Devices (ESD) and require special precautions when
handling. Particular care must be exercised when handling patch antennas, due to the risk of
electrostatic charges. In addition to standard ESD safety practices, the following measures should be
taken into account whenever handling the receiver:
•
Unless there is a galvanic coupling between the local GND (i.e.
the work table) and the PCB GND, the first point of contact
when handling the PCB must always be between the local GND
and PCB GND.
•
•
Before mounting an antenna patch, connect ground of the
device
When handling the RF pin, do not come into contact with any
charged capacitors and be careful when contacting materials
that can develop charges (e.g. patch antenna ~10 pF, coax
cable ~50-80 pF/m, soldering iron, …)
•
•
To prevent electrostatic discharge through the RF input, do not
touch any exposed antenna area. If there is any risk that such
exposed antenna area is touched in non ESD protected work
area, implement proper ESD protection measures in the design.
When soldering RF connectors and patch antennas to the
receiver’s RF pin, make sure to use an ESD safe soldering iron
(tip).
