Description
First of all, Arduino Uno R3 Chinese Clone is a microcontroller board utilizing the ATmega328P same like the Italian version. It has 14 digital input/output pins (of which 6 pins function as PWM outputs), in addition, 6 analog inputs, also 16 MHz quartz crystal, in addition to a USB connection, also, a power jack, an ICSP header, in addition to a reset button. It also contains everything to support the microcontroller.
The main difference is the use of the CH340 USB interface chip. On the other hand, In the Italian and Clone version the chip used is the Atmega 16U2.
