The electrical design connects the battery, power conversion, processors, motors, sensors, audio devices, camera, and user interface.
The section is intentionally split into two entry points so that users can first understand the overall architecture and then explore the individual boards.
Follow power distribution, voltage levels, buses, and signal paths through the robot.
Start with the physical board overview, then explore each PCB and its connectors.
Start with Electrical architecture to understand how power and signals move through the robot. Then use the PCB ecosystem as the reference index for individual board pages.
The hardware interfaces described here are used by the firmware hardware abstraction and hardware drivers.
