After watching Andy’s video over at the off grid garage about connecting the JK BMS to my raspberry pi. I ordered an isolated usb to ttl converter and followed the instruction. All the connections are correct but my converter went up in smoke. It turns out the voltage coming out of the BMS was 25volts. Can anyone tell me what voltage is coming out of their bms gps port? I am assuming mine is faulty.
The voltage for the tx rx line are 3 ish volts which I assume is correct.
