I have a chinese CH340 clone arduino. It was working fine until now. The L light stays always on. The sdm Atmel chip is overheating to the point that I can't even touch it. The card is listed under com ports however I can't upload anything due to:

avrdude: stk500_recv(): programmer is not responding

Should I just throw it away or is there a way to save it?

  • @SDsolar It was powered with a 12V adapter. It was also connected with a rfc522 module and a relay module. Apparently rfc522 also doesn't work anymore.
