Mega 2560 Pro CH340G ATmega2560 Board The Mega Pro Embed CH340G / ATmega2560 board is based on the ATmega2560 microcontroller and the USB-UART adapter CH340. The board is compatible with Arduino Mega 2560. The Mega 2560 is an excellent solution for building exciting projects based on ATmega2560.  The Mega Pro Embed functionalities are identical to the Arduino Mega 2560. Even though it is an Embed board, it is solid and stable as the Mega Board. It uses the original chip, and a 16 MHz high-quality quartz resonator is present on the board. atmega2560 board has a Micro USB connector that allows you to connect the microcontroller to the computer via the USB-UART adapter CH340 and may require an installation driver.  You can power the Mega 2560 Pro or power the pins through the MicroUSB connector. The voltage regulator (LDO) can handle input voltages from 6V to 9V (peak 18V) DC. The voltage regulator allows to use up to 18V as an input value, however, we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device.
