The Arduino Mega 2560 board is an enhanced version of the Arduino UNO. It has a large memory capacity and a large number of inputs.
Microcontroller features
The Arduino MEGA microcontroller uses the ATmega2560 microprocessor, which operates at a clock frequency of 16 MHz and has 8 kB RAM, 4 kB EEPROM and 256 kB Flash memory (for programming and data storage).

Power supply
The Arduino MEGA microcontroller operates over a voltage range of 7-12V, thanks to its on-board voltage regulator, while the microprocessor operates at 5V. In normal operation, the microcontroller consumes up to 45mA (if no power is supplied) and can accept a maximum current of 40mA on each of its IO pins.
