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 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
The Mega can be programmed with the EZ-B firmware for a variety of capabilities when connected to EZ-Builder. The tutorial to program the firmware on this device can be found HERE. This hardware was added to EZ-Builder in this beta release.
