Mega 2560 R3 Micro USB (CH340G)

Mega 2560 CH340G/ATmega2560 - compatible with Arduino Mega 2560 board. Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G.
Board for functionality similar to the Arduino Mega 2560. It is a budget, but the same stable, and uses the original chips ATmega2560 (16 MHz).
The board used the chip CH340G as converter UART-USB. Chip CH340G - is a budget solution. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer).
Mega 2560 CH340G / ATmega2560 - connects to the computer via microUSB cable (used for almost all Android smartphones).
You can supply power to board through a MicroUSB connector or XH power socket (cable with XH connector included). The voltage regulator (LDO) can deal with incoming voltage from 6V to 12V DC. Output current for 5V - about 800mA, for 3.3V - about 350mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.
