Arduino Uno Rev3 With CH340 Uploader

🌟 Product Description

This Arduino UNO Rev3 board uses the CH340 USB-to-serial interface instead of the ATmega16U2 found on the official UNO. Functionally it’s the same UNO Rev3 pinout and features, but at a lower cost, making it ideal for robotics, CNC controllers and embedded electronics where you need an inexpensive, reliable microcontroller platform.

🔑 Key Features
