Description
UNO R3 ATMega328P USB Compatible Development Board is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, 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 a USB cable or power it with a AC-to-DC adapter or battery to get started.
This upgraded model is completely compatible with original Arduino UNO.
