3-Axis Accelerometer/Magnetometer
The 3-Axis sensor device combines a 8-bit linear accelerometer. The device includes a
+/-2g, +/-4g, +/-8g and +/-16g dynamically selectable acceleration full scale range.
Acceleration event functions include free fall and motion detection. The accelerometer
communicates to the CPU on the I2C[2] bus at address 0x19. The accelerometer is a
STMicroelectronics LIS2DE12TR.

Optional GPS Receiver
The optional u-blox ZOE-M8 GPS Receiver is a 72 channel Global Navigation Satellite
System (GNSS) device for delivering position, velocity, and time information. The GPS
Receiver includes a dual frequency RF front end for concurrent reception of up to three
GNSS systems. This includes GPS/ZQSS, GLONASS, Galileo, and BeiDou.
The device is typically configured for 9600 NMEA protocol depending on the GPS
firmware revision. Communication to the CPU is through the UART1 serial port
interface. A pulse-per-second signal is also supported through the CPU
GPIO[1]:DIO[15] digital I/O signal. The PPS signal can be factory optionally routed to a
Mini-PCIe socket. A MMCX or a U.FL connector connects to an externally mounted
active antenna. The antenna includes a series current limit resistor to protect against a
shorted antenna.
