• 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 preburned 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).
• This Board can be powered via the USB connection or with an external power supply. The power source is selected automatically.
• Input Voltage (recommended):7-12V and Input Voltage (limits):6-20V
