Hello everybody. I hooked to the Master VESC an Arduino nano for tail brakes.
There are some problems. I feed the Arduino from the VESC. The VESC has a built-in switch. When I power on the BMS and the VESC it works, but if I power off only the VESC it doesn`t power off because the Arduino is feeding back power through the LED data pin going to VESC through the Tx Rx pins and it stays on and sometimes it burns the Arduino, same thing when I feed the Arduino from the DC-DC converter (5V) separately. How can I wire properly the Arduino to eliminate this problem?
I have been searching on forums but no success.
Here is a wiring diagram of how I hooked everything up.
Thankyou everybody.
