This is a UNO R3 CH340G ATmega328P Development Board, fully compatible with Arduino, and comes bundled with a USB cable—a perfect starter kit for anyone looking to dive into Arduino development. It eliminates the hassle of searching for individual components, making it a convenient and cost-effective solution for beginners and hobbyists alike.
The board is a budget-friendly alternative to the original Arduino Uno R3. It features the CH340 USB-to-Serial converter chip instead of the Atmega16U2, helping reduce costs without compromising on functionality.
We have tested numerous CH340-based boards and found them to be reliable and fully functional. The CH340 chip is only active during programming and USB serial communication. During standard operation, this board performs identically to the official Arduino Uno R3.
