The Pro Micro is similar to the Pro Mini, except for the fact that it utilises the ATMega32U4. Additionally, there is an on-board USB transceiver inside the 32U4, which removes the need for a bulky external USB interface. There is also a voltage regulator on-board which means it can accept up to 12V DC. Please bear in mind that if supplying unregulated power, you need to connect to...
