Early Production Information
1 Product description
1.1 Overview
The EVK-M8GZOE evaluation kit simplifies the evaluation of ZOE-M8G and ZOE-M8Q, the u-blox M8
ultra small high performance concurrent GNSS S-LGA modules. The built-in USB interface provides
both power supply and high-speed data transfer, and eliminates the need for an external power
supply. The u-blox evaluation kits are compact, and their user friendly interface and power supply
make them ideally suited for use in laboratories or vehicles. Furthermore, they can be used with a
PDA or a notebook PC, making them the perfect companion through all stages of design-in projects.

Features
•
Supports GNSS performance evaluation with simulator and active antenna
o
2 SMA connectors; one for simulator use case, one for external active antenna use case
•
Populated optional flash
o
Configuration can be saved permanently
o
Logging can be done
o
AssistNow Offline data can be saved
o
Optimal performance of AssistNow Autonomous
o
FW can be run from Flash (not by default)
•
Current measurement shunt resistors and corresponding measurement pins
o
1
Ω
shunt resistor makes it easy to convert measured voltage to actual power consumption
o
Set of jumpers to bypass these shunt resistors for more advanced power measurements
•
RTC crystal and backup supply to evaluate backup, hot start, and warm start functions
o
100
Ω
shunt resistor to measure backup power consumption
o
Super capacitor of 1F for backup supply
•
USB 2.0 connector for both power supply and data transfer
o
ZOE-M8G module does not support USB connection. For this reason the EVK-M8GZOE board
contains a separate Silicon Labs CP2102 USB to UART Bridge
•
RS-232 DB9 connector and digital connector for easy interfacing with UART, SPI and DDC (I
²
C)
and for evaluating other advanced scenarios
1.2 Kit includes
•
Evaluation unit
•
Active GNSS antenna with a 3 m cable
•
USB cable
☞
A plastic cap is attached on the top of the GNSS S-LGA Module in EVK-M8GZOE. The purpose of
the cap is to prevent air flow at ZOE-M8G.
