→CAN BUS
Every board, except in very extenuating circumstances, is required to implement the CAN bus.
Every board, except in very extenuating circumstances, is required to implement the CAN bus.
The required, standardized HONEY transceiver is the TI_SN65HVD230.

There are ''two'' CAN buses -- CAN1 and CAN2. CAN1 is the primary CAN bus used for the flight stack, while CAN2 is a secondary bus that exists only for possible future use. All boards should implement CAN1. The schematic for the CAN system for each board is well defined, and should be implemented exactly as shown. The CAN connector, in addition to the above described four nodes, includes a +3.3_CAN pin and a GND pin. GND should be common grounded, while +3.3_CAN should be used to power the CAN transceiver -- it should power no other device on a board, and the CAN transceiver should exclusively use this pin as its power source.
