The Arduino Mega 2560 R3 Board Clone CH340G Board is a high-capacity microcontroller board designed for demanding projects that require extensive I/O capacity and expanded memory.
The Arduino Mega 2560 R3 Board Clone CH340G Board is a high-capacity microcontroller board designed for demanding projects that require extensive I/O capacity and expanded memory. Built around the Microchip ATmega2560 8-bit AVR microcontroller running at 16 MHz, this clone board offers identical processing capabilities and pin layout to the official Arduino Mega 2560 R3.
Instead of the standard ATmega16U2 USB interface, this version utilizes the reliable and economical CH340G USB-to-UART converter chip. It connects via a robust USB Type-B port, providing seamless serial communication with PCs after installing the widely available CH340 driver. The board includes an onboard DC barrel jack for external power supply (7V–12V DC) with built-in 5V and 3.3V voltage regulators.
With 54 digital I/O pins (15 PWM capable), 16 analog inputs, and 4 hardware UART serial channels, the Mega 2560 is ideal for 3D printers (RAMPS boards), CNC routers, multi-sensor robotics, automated control systems, and data acquisition setups. It is fully compatible with the Arduino IDE and existing Mega R3 shields.
