Embedded version 2560 CH340G / ATmega2560 - Compatible with 2560 motherboard. Built on the ATmega2560 microcontroller and USB-UART interface chip CH340G. The board is compact and measures 38x55mm. This is a great solution for your final project on the welding prototype board. The motherboard functions like the Arduino 2560. It is an embedded motherboard, stable, and uses the ATmega2560 chip (16 MHz). The board uses the CH340G chip as the UART-USB converter. Provides stable data exchange when working at a frequency of 12MHz (requires driver installation on the computer). PRO (embedded) 2560 CH340G / ATmega2560 - Connects to a computer via a Mini USB cable (compatible with most Android smartphones). You can power the board or power the pins through the Mini USB connector. The voltage regulator (LDO) handles input voltages from 6V to 9V (up to 18V) DC. The output current is 5V - approximately 800mA, 3.3V - approximately 800mA (note that higher input voltage may reduce output current). This will power most of your initial projects.
