The Uno R3 CH340G ATmega328P Development Board is a budget-friendly alternative to the standard Arduino Uno R3. Instead of the Atmega16U2 USB-to-serial chip, this version uses the CH340 chip for USB communication.
We've extensively tested these cost-effective CH340-based boards and found them to perform reliably. The CH340 chip is only active during programming and when accessing serial data via the USB port. In regular operation, this board functions exactly like the more expensive original version that uses the Atmega16U2 chip.
Package Includes:
1 × Uno R3 CH340G ATmega328P Development Board (Arduino Compatible)
1 × Set of Male Header Pins.
Note: This is a clone version of the Arduino Uno R3. For optimal performance, long-term durability, and access to official support, we highly recommend using the original Arduino Uno R3 board.
