Hi,
I have chepap $4 arduino mini pro from eBay (5V/16Mhz). When I connect via FTDI adapter, It works properly. But When I connect 9V/1A power supply to RAW and GND pin, power led turn on and then after 0.5~2 seconds turn off. Fuse on it also get hot and break power supply (it is probably because led turn off). I tried it with 5V power supply also (Arduino Uno 5V pin) - same problem.
Does anyone know, what is wrong with it. What should I do to make it work properly?
