Arduino Mega 2560 Pro Mini Board

This is a low cost and miniature version of the popular Arduino Mega 2560. It is assembled with a genuine Atmel ATmega2560 microcontroller and the low cost CH340G USB-UART interface. 
This board is compatible with the Arduino Mega 2560. It has a compact form factor of 38 x 54mm and is an excellent solution for developing 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 stable as the Mega Board. It uses the original chip, and a 16 MHz high-quality quartz resonators is present on the board.
Connectivity
The board has a Micro USB connector that allows you to connect the microcontroller to the computer via the USB-UART adapter CH340(A driver installation may be required).
Connectivity to the computer is provided through the common micro USB connector (universally used by most phones, including Android smartphones).
Power characteristics
The board can be powered directly through the Micro USB connector, or via the corresponding contact on the board (Vin). The used voltage regulator operates in a range of 6 to 9V DC.
The maximum output current for 5V is around 800mA, while for 3.3V it is about 800mA.
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.
