This board runs the BPS system. It communicates with the Voltage & Temperature Minion Boards & Amperes Board over ISOSPI, and the rest of the electrical system with CAN. It controls the Contactors & Fans with 12V digital signals (PWM or just on/off).
The board requires seven connectors:
- One 2-pin Power Connector (+12V, PWRGND)
- One 2-pin strobe light connector (+12V, PWRGND)
- One 4-pin contactor connector (+12V, PWRGND, aux1, aux2)
- The aux pins detect if the Contactor is opened or closed through an Open Drain input.
- One 4-pin Amperes board connector (+12V, PWRGND, IP, IM)
- One 4-pin CAN connector (isolated +5V, isolated GND, CAN high, CAN low)
- One 2-pin Minion connector (IP, IM)
- One 2x4-pin fan connector (4x +12V, 4x PWRGND)
- An LED next to the contactor pin turns on when the Contactors are closed
- An LED next to the Power Connector turns on when 12V is applied to the board
- The column of LED's in the middle of the board are used to provide debugging information
