Uno R3 CH340G ATMega328P Development Board Compatible with Arduino

Arduino UNO R3 SMD Atmega328P Board CH340G is the low-cost version of the popular Arduino Uno R3. 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:

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