The UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analogue inputs, a 16 MHZ quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller, simply connect it to a computer with the supplied USB cable or power it with an AC to DC adapter or battery power to get started.

This board is the ATMega16U2 version.
