From the project
Senior Design implementation for Electrical Subsystems work for ORA's IGVC Robot
In the robot, there were plenty of components that needed to interface together. These include both ODrives over CAN and status light control. Its main purpose is to reduce the amount of wires that need to be going from each component and have every necessary component on a single board.
