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.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.

How to use
Connected to computer. (If this module cannot be recognized by your computer, please refer to this link to install the driver) Opened Ard IDE and loaded Blink sketch. Set board to Leonardo and selected the appropriate COM port (It showed up in the list already identified as a Leonardo). Connected an LED to pin 9 and modified the sketch accordingly. Hit upload and within a few seconds having a blinking LED.
If it can’t be recognized by your computer when you use it, please change another USB cable or computers to test, if still no any update, may you need to install a driver , we made a detail tutorial, you can visit: youtu.be/9k5mk-FHF24 if still not solved it, please tell us. We can definitely help you to fix the problem .
