## Description

The Arduino Mega 2560 is an upgraded version of the original Mega board, offering 54 digital input/output pins, making it ideal for larger projects. If you've worked with the Arduino Uno, or other smaller Arduino boards, then you'll love the Mega 2560. It retains the Uno's shield compatibility so you can use all of your existing hardware, and the extra pins have been added to the end of the board. With the extra pins comes a bump in hardware peripherals such as UART, TWI (I2C), SPI and PWM.

The Mega 2560 has an Atmel Atmega2560 microcontroller which packs 8x the amount of Flash memory (256KB), and 4x the SRAM and EEPROM (8KB and 4KB respectively). Whilst the extra hardware and connectivity is a great option, keep in mind that the mega2560 still runs at the same clock speed as the mega328 chip found on the Uno.
