Hi.

I don't know the reason why Arduino UNO R4 overheat. It overheat on black color chip as picture when I connect USB.

I think my controller is broken, but I want to know reason to prevent this isssue.

I connect batter 18560 x 4 to L298N driver (16V) and use remote controller FS-i6X to control motor. (Reciver is FS IA10B)

I send you about circuit diagram. I try 3 pattern.

  1. Use battery 9V for R4
  2. Use baterry 9V and USB cable(from PC) for R4
  3. Use 5V from L298N to Reciver FS-IA10B

That's a clone - so who can tell?

Nothing connected to those RC receiver channels? I wouldn't power one off an Arduino +5V regulator, especially if you have any +V servo wires going from it to an ESC or servo.

Hi. Actually, I connected signal for channel 1 and 2 to pin 8,9
