Arduino Pro MicroSee More
Features: 32U4 running at 5V/16MHz Recommend power supply for board: 5V,
less than 6V On-Board micro-USB connector for programming 4 x 10-bit ADC pins, 12 x
Digital I/Os Rx and Tx Hardware Serial Connections
Description:
1. The Pro Micro is similar to the Pro mini except with a 32U4 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 for for 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 for
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.
