UNO R3 Development Board with CH340 for Arduino Projects

Powerful development board powered by ATMega328P

A low cost Uno Development board for Arduino projects with the CH340 USB to Serial Converter Chip. Utilising the ATmega328P microcontroller, its features, functions and specifications are identical to the Arduino Boards that are made in Italy, minus the price tag.

The Arduino Uno 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 ceramic resonator, 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 a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it uses the CH340 chip.
