ATMEGA 2560
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has
54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analo g
inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection,
a power jack, an ICSP header, and a reset button.
We previously used Atmega 328 MCU. But due to insufficient flash memory we
jumped to an Arduino Mega board.
