VKLSVAN 2PCS Pro Micro ATmega32U4 5V 16MHz Micro USB Development Board Module Compatible with Arduino IDE Leonardo

Features: 1.The Pro Micro is similar to the Pro mini except with an 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. There is a voltage regulator on board so it can accept voltage up to 9V DC. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC. Specification: .ATmega32U4 running at 5V/16MHz .On-Board micro-USB connector for programming .Work with newest software from Arduino.cc .4 x 10-bit ADC pins .12 x Digital I/Os (5 are PWM capable) .Rx and Hardware Serial Connections How to use? 1. Connected to your computer. 2 Opened the Arduino IDE and loaded Blink sketch. 3. Set board to Leonardo and selected the appropriate COM port (It showed up in the list already identified as a Leonardo). 4. Connected an LED to pin 9 and modified the sketch accordingly. 5. Hit upload and within a few seconds having a blinking LED. Package Included: 2 x Pro Micro ATmega32U4 5V 16MHz Development Board Module
