The Arduino Uno R3 compatible microcontroller board is based on the better ATmega328 with 32kB memory. Furthermore, it has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the micro controller; 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 UNO R3 uses the CH340G chip for USB communication. UNO R3 is 100% compatible with the Arduino IDE, and Arduino shields (5V).
