Thanks for you response. When you mentioned "CAN side of the CON CAN module is not galvanically isolated", how about "other side" :)? May I have CAN side circuit schematic of this CON CAN module? Does the RevPi Connect S 32GB CPU module has galvanically isolated component? Do you...

Hi

I am wondering if RevPi ConCAN module has galvanic isolation?

I did measurement resistance between CPU power supply and CAN-H and CAN-L. The result shows HIGH resistance (O L) so I expect that there is some kind of isolation, but I am not sure.
