Uno R3 CH340G ATmega328p Development Board is a low-cost version of the Uno R3. It uses a CH340 USB to Serial converter chip instead of an Atmega16U2.
It has worked perfectly for us when we used a lot of low-cost Arduino boards with CH340 chips. This board works exactly like the more expensive version without the CH340 chip during normal operation. The CH340 chip is only used during programming and when using the serial output of the USB port.
