Hi,

I’d like to ask whether the Xavier unit supports 24V CAN bus?
I saw in the docs that 24V shouldn’t be used as power supply and the GPIO’s also doesn’t support it but at the CAN section nothing was mentioned.
Can I connect it to a 24V CAN bus? Or do I need to use any signal level shifter for this? If yes, then can you suggest a chip for it?

Thanks,
Tamás

CAN transceiver family meets the ISO11898-2 (2016) High Speed CAN (Controller Area Network) physical layer standard.
CAN bus transceivers can operate only from a 5V supply, but receiver common mode input voltage: ±30 V.
