Working of ATMega2560
ATMega2560 is an 8-bit AVR configured controller and has 86 programmable GPIOs pin, ADC, and timer.
So it can programmed through the use of Atmel studio or the use of another ATMega microcontroller and the Arduino development environment.
The simplest use is an Arduino mega board that comes with ATMega3560 and gets programmed with the use of USB of Arduino software.
The GPIO pins such as SPI, USART, and SPI are configured internally for different communication protocols.
This module uses 5V logic levels so not used for 3.3V sensors and other devices. That is a limitation and can be controlled with use of level-shifting circuits.
