The NHduino UNO R3 ATmega328P CH340 Mini USB Board is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 12 MHz crystal resonator, a mini 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 mini USB cable or power it with a AC-to-DC adapter or battery to get started.
The NHduino Uno can be programmed with the Arduino Software IDE. Select “Arduino/Genuino Uno” from the Tools > Board menu and “COM x” from the Tools > Port menu. Built-in Examples demonstrate all basic Arduino commands.
