Description
Uno R3 CH340G Development Board with Micro USB port compatible with Arduino
The Arduino Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 Micro-USB to Serial converter chip, instead of using an Atmega16U2 chip.
We have used plenty of these low-cost 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 Micro-USB port. During normal operation, this Arduino Uno R3 board is identical to the more expensive version without the CH340 chip.
Main changes from the older version:
1. Two rows of 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
