The Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 USB to Serial converter chip, instead of using an Atmega16U2 chip.

We have used plenty of these low-cost Arduino boards with CH340 chips, and have found them to work perfectly. The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation, this board is identical to the more expensive version without CH340 chip.

Main changes from the older version:

1. Two rows of the holes for the pins (Male and Female). So it can be connected with normal Female Jumpers.
2. Additional 3 rows of the holes for wiring.
3. Changes to the DIP package of ATMEGA328P to flat package.
4. CH340G replace ATmega16U2


How to use:

1. Download the IDE Arduino
Link: http://arduino.cc/en/Main/Software (Copy to open)
2. Download the USB chip driver
Link: http://www.5v.ru/zip/ch341ser.zip (Copy to open)
3. Plug in UNO development board, the driver will be installed automatically
4. Select the UNO from the die
5. Select the COM port
6. The best choice first, Arduino comes with routine procedures, burn into it.

1 x Uno R3 CH340G ATmega328p Development Board Compatible with Arduino

    Best product. Robu.in provides genuine products. yet this arduino is a clone… but it works perfectly… for me the CH#$) was not a problem… my windows 10 recognized it without any driver installation… Also price is reasonable… works great

    thanks ROBU

    Superb Product but giving it 4 stars because the Male Header Pins were not soldered and given in a separate pack, which created a problem for me as I needed extra pins.

  16. imrankhan96799 (verified owner)

    It works great but intialy i had faced some problems. I had installed the ch340g drivers provided by robu.in but my PC still didnt recognize the arduino and only showed errors while uploading. But 10 or 15 minutes later, the drivers got activated and the uno got recognised. Ever since then it has been 2 weeks , i am using it happily. If you face a similar problem after installing the drivers , the please give the drivers some time to get activated and then it should work flawlessly 🙂
