It includes an onboard Micro-USB port for direct programming, 12 digital I/O pins, 4 analog inputs, and hardware serial connections (Rx/Tx). Supported by Arduino IDE v1.0.1, this triple-pack set is perfect for professionals and makers seeking a versatile, high-performance development platform that fits anywhere. ## Description Description: 1. The Pro Micro is similar to the Pro mini except with a ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface. 2. This tiny little board does 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. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
