The Arduino ADK is a microcontroller board based on the ATmega2560 (datasheet). It has a USB host interface to connect it with Android based phones, based on the MAX3421e IC. It has 54 digital input/output pins (of which 14 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 ADK is based on the Mega 2560.

Similar to the Mega 2560 and Uno, it features an ATmega8U2 programmed as a USB-to-serial converter.
Revision 2 of the MegaADK board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
