• ATmega2560 running at 16MHz external resonator
• USB connection off board
• Over current protected
• RoHS compliant
The Mega Pro Arduino Compatible Microcontroller is powerful, portable and Pro. This is a 5V microcontroller running a version of the stk500v2 bootloader at 16MHz. Just like the other Pro-series boards this board is built with all SMD components and comes with no headers populated in order to minimize the cost and the board profile. Of course this board has the same pin-configuration as the Arduino Mega, so it is dimensionally shield compatible.

Note: It's identical, but does not say '3.3V'.
Features:
• 5V regulator, 200mA continuous (500mA peak)
• Reverse polarity protected
• DC input 5V up to 12V
• Resettable fuse prevents damage to board in case of short
• Power select switch acts as on/off switch
• Supplier code : DEV-11007
