Features:

ATmega32U4 running at 5V/16MHz

with ArduinoIDE v1.0.1

4 x 10-bit ADC pins, 12 x Digital I/Os

Rx and Tx Hardware Serial Connections

On-Board Micro-USB connector for programming

Pay attention to :

1.The acceptable voltage range is 6 to 9 V

2.When you open the with ArduinoIDE software, could you please go to the tool and choose the board "with ArduinoLeonardo"

Explanation:

1. The Micro is similar to the 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 with 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-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.
