Review on OSOYOO Pro Micro ATmega32U4 Module Board: 5V/16MHz, 2 Row Pin Header, Arduino Compatible – Upgraded Version with ATmega328 Pro Mini Support by Gary Morris

Was expecting a cheap clone of the Due board and it did to get. Requires pressing the reset button to load the main application on the Cortex M3 processor instead of the bootloader - as recommended in several forum threads, a 10kΩ resistor soldered to the FET on the board solves this problem. This matches the later schematics of the original Arduino board. I'm not sure I recommend this board unless you know how to solder in your application and/or press the reset button.
