This is an Arduino Leonardo compatible board. The Arduino Leonardo is a microcontroller development board, based on the Atmel ATMEGA32U4, that contains everything needed to run including power regulation, a crystal oscillator, and a USB-to-serial programmer, a USB connection, an ICSP header, and a reset button. The ATMEGA32U4 has USB connectivity and creates its own USB-to-serial programming bridge. This USB connectivity also allows it to act as a USB human interface device (HID), like a mouse or keyboard.  The Leonardo supplies 20 GPIOs (7 PWMs), 12 analog inputs, UART, TWI, and SPI while running at 16 Mhz. The Leonardo can be powered from an AC-to-DC wall adapter (6 – 20V) or it can be powered directly from USB.
