PCBWAY was gracious enough to sponsor this revision. With their support this project is one step closer to completion and I'm very pleased with the results. 

A few changes from the last board to streamline things. While using dev boards can make things simpler, sometimes they can be difficult to integrate smoothly. I've decided to simply use a ESP32-S3 module directly for this project. This removes the issue of dealing with multiple USB ports and potential power supply conflicts. So we get all the power of an ESP32-S3 for a cheaper price with none of the hassle. This was an easy decision since this board requires reflow soldering. Adding the vanilla module doesn't add complexity and reduces the overall cost. The only "must have" sensor to satisfy the initial goals is a simply IMU/accelerometer which has also been added (MC3479). 

Also included is a simple battery monitor line to an IO pin, reverse protection for the lithium cells, red indicator light for E-Stop function, and a change to a 12 pin flex ribbon vs the bulky standard header cable. 

Thanks again to PCBWAY for these cool looking white and gold PCBs. Looking mighty fancy! ☺
