From the project

Stanford Robosub Electrical Repository

KiCad board designs for the gen 2 vehicle. Not every board here is in active use — some are older revisions, and some are experimental.

- MLUBreakoutV2/ — Main Logic Unit breakout, version 2. Routes I/O between the main compute/Teensy and the vehicle's sensors, actuators, and peripherals. This is the breakout currently flying. - PowerDistribution/ — takes battery input and distributes it to the vehicle's power rails. Currently in use.
