Description
Uno R3 CH340G ATmega328P Development Board (Compatible with Arduino)
The CH340G chip is used only during programming and serial communication. During normal operation, the board performs identically to the standard Arduino Uno R3. We have extensively tested CH340-based boards and found them to be stable, reliable, and fully compatible with the Arduino ecosystem.
This board is ideal for learning Arduino, prototyping, embedded development, robotics, and automation projects.
How to Use
- Download and install the Arduino IDE
- Download and install the CH340 USB driver
- Connect the Uno R3 board to your computer via USB
- Select Arduino Uno from the board menu

Customer Reviews
good
buy it its worth it just install the drivera if its not showing in ardino software
Value for money
Very good and secure packing and product is very good
just now received...not even used..hope for best....looks like perfect...and as expected....similar to the picture....go for it...
Super quality product i like itValue of money....👍👍
The board is working perfectlyThe male pins which are added in Arduino are not pre attached if you want you have to make an effort for it.Thank you.
The only difference with original is, you may need to download the usb driver for board. I had to download the driver in one computer, but didn't need to in another computer.
I'm using it from 2 years.It's working smoothly.
This is best Cheapest arduino uno 🤩 Woking very well condition is suberb
