This is the clone version of genuine Arduino UNO R3 imported from China. The Chinese version might not work as efficiently as the genuine Italy made UNO R3 yet is useful for small and short-term projects.
The Arduino Uno 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 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
