Embed version of Mega 2560 CH340G/ATmega2560Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G.Board have compact size 38x55mm. It is good solution, to make your final project on solder proto-board.The board used the chip CH340G as converter UART-USB.Flash Memory:256 KB of which 8 KB used by bootloader;EEPROM:4 KB;Clock Speed:16 MHz 2560 CH340G/ATmega2560 . Built on the ATmega2560 microcontroller and USB-UART interface chip CH340G. Board have compact size 38x55mm. It is good solution, to make your final project on solder proto-board. Board for functionality similar to the ATmega2560 . It is embed board, but the same stable, and uses the original chips ATmega2560 (16 MHz). The board used the chip CH340G as converter UART-USB. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer). You can supply power to board through the MicroUSB connector or to power pinheaders. The voltage regulator (LDO) can deal with incoming voltage from 6V to 9V (peack 18V) DC. Output current for 5V - about 800mA, for 3.3V - about 800mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.
