Pro Micro For Arduino - 5V/16MHz

Welcome the Arduino Pro Miro – the tiny version of Leonardo. The Pro Micro is similar to the previous Pro Mini except that it uses the ATmega32U4 on board, which allows us to add USB connectivity on-board and do away with bulky external USB interface. This tiny little board uses the Atmefa32U4 chip, it has the same amount of flash, RAM and capability as the ATmega328. It also has all of the neat-o Arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. Simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter to get started. In addition, Like Arduino Leonardo, the pro micro can appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
