Motor Board v1 - Itsy Bitsy Motor Board
An ItsyBitsy M4 Express microcontroller is used to drive two DC motors via a DRV8833 motor driver board.
It also reads the wheel encoders of the wheels.
It exposes a UART interface to drive the motors with simple high level commands.
This repo contains the design for a PCB (in Autodesk Eagle 9.6.2) with headers to connect everything up.
