This is Arduino UNO R3 and its uploading interface is Micro USB socket. The Arduino Uno r3 micro USB is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog 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 an AC-to-DC adapter or battery to get started.

It is 100% compatible with the Arduino UNO R3 program, expansion shields, IDE.
