Arduino Mega 2560 CH340 Development Board – ATmega2560 SMD

The Arduino Mega 2560 CH340 Microcontroller Development Board is a high-performance, high-density embedded expansion platform engineered for complex automation, massive sensor matrices, and demanding robotics projects. Built around the powerful ATmega2560 microcontroller in a space-saving SMD package, this board features a high-reliability CH340G USB-to-Serial converter chip in place of the standard 16U2 interface. With 54 digital I/O lines, 16 analog inputs, and 4 independent hardware UART ports, it is an ultra-affordable powerhouse for multi-peripheral hardware designs.
