Overview
Overview
Our motivation for this sensor board is to create a new iteration of our sensor board for Excalibur, CalSol's newest generation solar car. This board is meant to be a proof-of-concept for the implementation of all of the necessary sensors with the newest ESP32-S3 chip. Our chosen sensors for this project were a GPS antenna, a humidity and temperature sensor, an accelerometer and inclination sensor, and a pressure/wind speed sensor.

In future iterations of this sensor board, we plan to fix wiring issues, optimize for trace heat output and fix trace sizings, build an enclosure for our PCB, and finally implement it into Excalibur!
