This is the new Mega ADK R3. ADK is a microcontroller board based on the ATmega2560.
It has a USB host interface to connect for 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.Similar to the Mega 2560 and Uno R3,
it features an ATmega16U2 instead of ATmega8U2 programmed as a USB-to-serial converter.
The 3.1 platform (also backported to 2.3.4)
introduces for Android Open Accessory support, which allows
external USB hardware (for Android USB accessory) to interact
for Android-powered device in a special accessory mode.
When for Android-powered powered device is in accessory mode
the connected accessory acts as the USB host (powers the bus
and enumerates devices) and for Android-powered device acts
as the USB device
