/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com 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. 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. https://learn.sparkfun.com/tutorials/esp32-thing-motion-shield-hookup-guide?_ga=2.240586115.1022152466.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com 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.

This section also shows what the GPS module, battery, and SD card look like when properly inserted. The completed stack. Attach the Stackable Headers to the Motion Shield Solder a single pin on each header. Make sure the headers are straight, and lined up.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com Solder the rest of the pins focusing on getting nice, even, conic fillets. Attach the Headers to the ESP32 Thing https://learn.sparkfun.com/tutorials/esp32-thing-motion-shield-hookup-guide?_ga=2.240586115.1022152466.1517244327-204410570.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com Put the pin headers in the shield, and set the ESP32 Thing on top. Then, apply solder and build up nice fillets making sure to not bridge any pins. Adding an Optional Sensor If you’re using a BME280 to try out the I2C or SPI port, install headers on it as well. See the BME280 Hookup Guide for more information. For generic operation solder both headers (left). If you only need I2C (middle), or SPI (right), only attach those headers.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com The JST connectors are seated properly, protruding slightly from their sockets (left). When the SD card is inserted properly (right), it should be flush with the edge of the board. Stack and Connect Additional Parts! Stack the ESP32 Thing on the ESP32 Thing Motion Shield. ESP32 Thing, motion shield, GPS receiver, and battery installed.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com The Motion Shield itself doesn’t use any special software. It relies on the SD card library from the ESP32 core, and the LSM9DS1 library, plus whatever you attach to it. Make sure you’ve got the following installed before continuing on to the examples. ESP32 Thing Arduino Core – Follow the instructions from the ESP32 Thing Hookup Guide. Arduino Libraries: LSM9DS1 – Follow the LSM9DS1 Hookup Guide or use the library manager.
1/29/2018 ESP32 Thing Motion Shield Hookup Guide - learn.sparkfun.com The pins listed in Hardware Overview are also listed here as #defines you can use. Not all are necessary for every application, but it’s nice to have them all in one place for reference.
