Hey, I have an Odrive S1 and am trying to connect it to an mcp2515 CAN Transceiver. I don’t have the jst connectors required for J16 or J17 since most tutorials mention to use those.
Can I connect Transceiver to J11 1 or 3 CAN L and 2,4 CAN H? What’s the diff between J11 can and J 16 17 can
No difference – CAN is both on J11 and J16/J17 for ease of wiring, they’re internally connected on the board.
Thankyou so much; just one last thing. Lets say I am connecting via the J11 CAN L and CAN H how would the common grounding work there? like pin 16 or pin 26 on J11?
Usually you want the ground connections in your system at a single “star point,” which is usually near the power supply / battery. Otherwise it can be easy to accidentally form ground loops. For instance, if you’re using an Arduino, you could run a wire from the Arduino GND to your power supply or battery GND (e.g. where the ODrive’s connected to the supply/battery) – now both the ODrive and Arduino share a ground, and there’s much less risk of accidental ground loops. Typically you only have to wire CANH/CANL and the grounding is done elsewhere.
