Arduino Mega 2560 ( With Cable ) – The MEGA 2560 Board can be powered via the USB connection or with an external power supply. The power source is selected automatically. The ATmega2560 has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library). The MEGA 2560 Board for Arduino comes pre-burned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

The board with the most pins is the Mega 2560, which comes in with a whopping 54 Digital I/O pins (were 15 of them have PWM) and has 16 Input Analog pins.
- Bootloader – to allow downloading of ‘sketches’ via USB without having to go through other external writers.
- Powered from USB or via external PSU (not supplied). The device will automatically switch between power inputs.
- Heavy gold plate construction.
