Arduino MEGA 2560 CH340 R3 Compatible Board

The Arduino Mega 2560 (CH340G version) is a powerful and enhanced microcontroller board based on the ATmega2560 chip, designed for complex electronics projects and IoT applications. With 54 digital I/O pins (15 supporting PWM output) and 16 analog inputs, it provides extensive flexibility for connecting multiple sensors, modules, and devices.

Featuring 256 KB of flash memory (8 KB used by the bootloader), 8 KB SRAM, and 4 KB EEPROM, this board is perfect for large programs and memory-intensive applications. It operates at 5V logic and supports an input voltage of 7–12V (recommended), making it versatile for a wide range of embedded systems. The CH340G USB-to-serial chip ensures seamless connectivity and programming via USB.
