Mega ADK Rev3
Empowered with a blend of ATmega2560 microcontroller and MAX3421E
IC, the Arduino Mega ADK Rev3 hits the market offering various upgraded
features. The board facilitates the Android
phone-connectivity via USB host interface. The digital I/O 54-pin
configuration includes 15 PWM output channels and 16 analog outputs. Mega ADK
also features auto-reset program which eliminates the requirement for a power
button.

Arduino Mega ADK Rev3 Description
If only
requires a USB connection to supply the power to Mega ADK, instead you can also
use an external supply. The board is programmed to auto-select the source of
power. You may use an AC-DC adapter if you want to use an external power
supply. A battery will also serve the purpose. The board contains the power
jack which receives the 2.1mm plug (Centre-Positive)
to start getting the power. In the case of a battery, you need to connect the Vin and Gnd pin headers with the battery leads.
Please Note
Being a USB host, a phone will try to get charged by drawing power from
the MEGA ADK. The phone requires 750mA, so it won’t suffice in the case of USB
power supply (500mA). The external supply will suffice with 1500mA (750mA
reserved for the phone.
