Pro Micro ATmega32U4 5V 16MHz Mini MCU Leonardo

• A USB transceiver inside the 32U4 allows USB connectivity on-board
• This tiny little board has 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.
• There is a voltage regulator on board so it can accept voltages up to 12VDC.
• If supplying unregulated power to the board, connect to the "RAW" pin not VCC. Unlike some other variants of this board board pin 14 is correctly labeled. and the RX and TX LEDs function correctly A PTC fuse and diode protection is incorporated into the power circuit

Features:

• ATMega 32U4 running at 5V/16MHz
• Support for IDE v1.0.1
• 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
• Mini USB Connector on board for programming
