The MCP2517FD is not recommended for new designs. Replacement is MCP2518FD and should be pin compatible and is better available and cheaper.

footprint is a little bit to big

add some EMI/ESD protection devices for the CAN bus.

The Zubax Orel 20 ESCs and many UAVCAN enabled sensor/actuators utilize the JST GH connectors with a pitch of 1.25 mm.

Zubax Orel 20 Pinout

Providing 2 such connectors (CAN-IN, CAN-OUT) would allow easy interfacing with other UAVCAN enabled products.

However, there are a couple of open questions on my end and I'm hoping @pavel-kirienko can provide some clarity here. Internet documentation on the Dronecode Autopilot Connector Standard is both scarce and contradictory. It seems that the proposed standard has 6 pins, but I'm not sure on the exact pin-out. The Zubax Orel 20 ESCs have a 4-Pin connector. Why this discrepancy? What kind of pinout can we expect to be more widely adopted in the future?
