Arduino MEGA ADK Board
The Arduino MEGA ADK is a microcontroller board based on the ATmega2560 . It has a USB host interface to connect with Android based phones, based on the MAX3421e IC.
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 ADK is based on the Mega 2560.
Similar to the Mega 2560 and Uno, it features an ATmega16U2 programmed as a USB-
Revision 2 of the Mega ADK board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
