The Arduino Uno is a microcontroller board with 14 digital input/output pins (6 of which can produce PWM), 6 analogue inputs, and a USB connection. It is compatible with the original UNO R3 and can be directly replaced. It uses the Atmega16U2 chip, which is programmed as a USB-to-serial converter, and has a stronger RESET circuit. Additionally, the board has two new pins, the IOREF pins, which allow the shields to adapt to the voltage provided by the board.
