... IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes. ...

... The power pins are as follows: VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin ...

... Automatic (Software) Reset Rather then requiring a physical press of the reset button before an upload, the Arduino ADK is designed in a way that allows reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the ATmega8U2 is connected to the reset line of the ATmega2560 via a 100 nanofarad capacitor ...

... Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well- coordinated with the start of the upload. This setup has other implications. When the ADK is connected to either a computer running Mac Linux, it resets each time a connection is made to it from software (via USB) ...
