You can supply power to board through the power pin-headers or USB interface. Output current for 5V version – about 800mA, for 3.3V version – about 800mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects. On the picture, you can see the real size of this board, compare with the size of Mega Rev3.
