Arduino - Uno Rev3 - Bulk

The Arduino Uno board is equipped with an ATmega328 microcontroller. It has 14 digital inputs/outputs (6 of which can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, a USB port, a power socket, an ICSP connector, and a reset button. To drive the microcontroller, simply connect the board to a computer with a USB cable (not supplied).
