This is the new 2016 version of our Mega 2560 board that is fully compatible with the Arduino Mega 2560. It utilizes a genuine Atmel ATmega2560 microcontroller and the inexpensive CH340G USB-UART interface. 
This board continues our commitment to uncompromising quality using the best components and excellent design layout, whilst providing a stable low cost solution. It uses the CH340G to lower the cost without losing functionality or quality. 

The board is built using high-quality components with great attention to detail in the design to provide a stable solution whilst keeping the price lower. 

Connectivity
Connectivity to to the computer is provided through the common microUSB connector (universally used by most phones, including Android smartphones). 

Power characteristics 
The board can be powered by the same MicroUSB port or a DC Barrel jack connector. An onboard low voltage regulator (LDO) can reliably regulate input voltages of 6V to 12V. Recommend 7V-9V.
The output current for 5V is approximately 800mA and 180mA for 3.3V. Do note the higher the input voltage the lower the output current.
