This is an Arduino Uno compatible board. The Arduino Uno is a microcontroller development board, based on the Atmel ATMEGA328P, 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 USB-to-serial programming bridge is based on the CH340G USB-to-UART bridge IC.  The Uno supplies 14 GPIOs (6 PWMs), 6 analog inputs, UART, TWI, and SPI while running at 16 Mhz. The Uno can be powered from an AC-to-DC wall adapter (6 – 20V) or it can be powered directly from USB.
