Please allow 1-2cm slight dimension difference due to different manual measurement. About this item It is an ATmega2560-16AU USB CH340G MCU Development Board Microcontroller Compatible with Mega2560. Embedded version Mega 2560 CH340G / ATmega2560 - Compatible with for Mega 2560 motherboard. The motherboard functions like the for Mega 2560. It is an embedded motherboard, but it is also stable and uses the original chip ATmega2560 (16 MHz). Mega PRO (embedded) 2560 CH340G / ATmega2560 - Connect to a computer via a microUSB cable (almost all for smartphones). The board uses the chip CH340G as the converter UART-USB. When you work at a frequency of 12Mhz, you provide a stable data exchange result (requires driver to be installed to the computer). You can power the board or power the pins through the MicroUSB connector. The voltage regulator (LDO) can handle input voltages from 6V to 9V (peak 18V) DC. The output current is 5V - about 800mA, 3.3V-about 800mA.
