Description
Arduino Mega Rev.3 with CH340G
Because the CH340G chip is cheaper and easy to find I decided to modify the design of the Arduino Mega to use it as USB to serial converter chip. I changed also the USB B type connector to Micro USB - now it is more common and standard. Assembling this board requires soldering and programming experience. All needed information how to burn the bootloader inside theAtmega2560 / Atmega1280 chip, you can find in the Arduino site.
