Arduino ADK Rev3

The Arduino ADK R3 is a microcontroller board based on the ATmega2560 (datasheet).
It has a USB host interface to connect with Android based phones.

It is compatible with Android's Accessory Development Kit examples. 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.
Plus it has an USB Host circuit that enable this board to communicate with USB Devices, and give them power supply.
 

For information on using the board with the Android OS, see (Google's ADK documentation).

מאפיינים נוספים לגרסה זו:

• ATmega16U2 instead 8U2 as USB-to-Serial converter.
• 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF
  pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to
  adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.
• stronger RESET circuit.
