Hardware Overview

The hardware is a conglomeration of an SD card socket, LSM9DS1 IMU, and GPS serial port. There's also an LED for general indication.

Motion Shield Parts

All components are populated on the top of the board. Here, you can see the SD card, IMU, and port. The ESP32 Thing is intended to sit above this board, so no pins are labeled.

Back of Motion Shield

There are no options on the bottom side. Here, you'll find labels for all of the pins. The two rows of pins on the side are wired together so that you have one available for prototyping after installing an ESP32 Thing.

The signals that are used are show here, grouped by function.
