I recently bought an Arduino Nano ( a clone actually), I installed the CH340G drivers for it and got it working perfectly fine... Played around with it for a while and then kept it aside...

Now after sometime I get time to play with it again, I was actually trying to power it with my 11.1V 2200mAh 8C LiPo battery. So I plug the JST connector to the Vin and GND pin and the LED doesn't light up. I noticed that I had plugged it in the wrong way and I immediately unplugged it. Next I make another attempt and this time I plugged the pins entirely somewhere else, again I disconnect quickly. The third time I connect it properly and the power LED lights up (phew...)

Now I move on to my computer to program it but the Arduino IDE is stuck at uploading. It was working fine before, when I hit upload, the RX LED glows VERY dimly and the board just stays like that. Only the power LED glows up, not even the LED on pin 13 glows up.
Uploading to a UNO works perfectly fine.

This is the error I get after a while-

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x7d

Did I burn my board? Or is it just a bootloader issue?

Unfortunately Vin on an Arduino Nano does not have a reverse polarity protection diode such as the Arduino Uno PWRin

Did I burn my board?

Very probable. For more details please see "10 Ways to Destroy an Arduino".

  • that's not at all good... Now I'm gonna have to run around with a UNO strapped to my wrist instead of the Nano
