Goals
A power distribution board is necessary to supply power to the various subsystems in the vehicle. The front power distribution is responsible for distributing power in the front enclosure. This board performs distribution, startup, shutdown and emergency shutdown as required in regulations. In addition to powering the boards, it also powers components directly, such as the driver display, driver controls, front lights, dashboard, horn, and driver fans.
