Pro Micro 5V 16MHZ Controller Board With Bootloader

The Pro Micro is similar to the D1 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. 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.

Features:

• ATMega 32U4 running at 5V/16MHz 
• Supported under Arduino IDE v1.0.1 and up 
• On-Board micro-USB connector for programming 
• 4 x 10-bit ADC pins 
• 12 x Digital I/Os (5 are PWM capable) 
• Rx and Tx Hardware Serial Connections

Package Included:
