Arduino Uno Rev3 with CH340 Uploader

The Arduino Uno Rev3 with CH340 Uploader is a reliable and affordable microcontroller board based on the ATmega328P. It is widely used for learning electronics, DIY projects, and prototyping. It runs at 16 MHz and includes 32KB of Flash memory. In addition, it comes with 14 digital I/O pins (6 support PWM) and 6 analog inputs, making it flexible for many applications. Because it operates at 5V, the board can be powered through USB or by an external power supply (7–12V recommended). Also, the CH340 USB-to-serial chip provides stable communication with your computer. If the driver is not installed automatically, you can easily download it for Windows or Mac. Therefore, the board works seamlessly with the Arduino IDE. This version uses a DIP-socket ATmega328P, which means the processor can be replaced if needed. For example, it is useful in classrooms, workshops, and robotics projects where durability matters.
