Introduction:
keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator ) of microcontroller. There are 54 I/O (input/output ) digital interfaces (of which 15 are PWM outputs), 16 analog inputs and 4 UART (hardwareserial ports). With its bootloader, program can be downloaded directly with USB and you don't need to use other external programmer. It can be powered directly by USB, or AC-to-DC adapter and battery.

2Design of Power Supply :
There are two choices (direct power supply trough USB or external power supply) for the power supply system of Mega, and they can be Automatic switched.
External power supply can be AC-to-DC adapter or battery.
Lit rang of voltage of this control board is 6V~12V, but if the supplied voltage is greater than 12V, the voltage stabilizing device will be likely overheated and overheat protection and damaging MEGA will be more likely to occur.
So we suggest the power supply should be 6.5~12V in operation and recommended supply is 7.5 or 9V.
