Mega 2560 Pro Embed CH340G / ATMEGA2560-16AU chip with pin headers Compact design and compatibility - Built-in Mega 2560 version with CH340G USB-UART interface; compatible with Arduino Mega 2560 boards. - Built around Atmel ATmega2560 microcontroller and CH340G USB-UART interface chip for reliable operation. Easy operation and flexible power - Small form factor: 38 x 55 mm. - Provides similar functions to Arduino Mega 2560; stable performance with original ATmega2560 (16 MHz) chips. - Power the board via the micro USB port or from the pin headers. High performance and connectivity - CH340G chip acts as UART to USB converter for convenient computer connection. - Operates with a 12 MHz clock to ensure stable data exchange (drivers must be installed on the computer). - Connects to the computer through a micro USB cable (commonly used by Android devices). Use scenarios - Robotics projects that require multiple I/O and reliable control. - Prototyping large Arduino Mega-scale applications in a compact footprint. - Data logging, sensor arrays, or DIY controller projects for hobbyist or educational use.
