Arduino UNO R3 CH340G compatible ATMEGA328P RED PCB with bootloader

Arduino UNO R3 compatible CH340G   The Arduino UNO R3 is the best board to get started with electronics and coding. If this is your first experience with electronics and coding, the UNO is the most robust board you can start playing with. The UNO R3 is the most used and documented board of the whole Arduino family. The UNO R3 is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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. Differences with other boards: The UNO R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.  Revisions:
