A 5VDC supply can be used to provide power to the board. The power supply current
depends on how many and what type of add-on boards are connected to the board. For
typical use, a 5VDC supply rated at 1A should be sufficient. If heavier use of the
expansion headers or USB host port is expected, then a higher current supply will be
required.
The connector used is a 2.1MM center positive x 5.5mm outer barrel. The 5VDC rail is
connected to the expansion header. It is possible to power the board via the expansion
headers from an add-on card. The 5VDC is also available for use by the add-on cards
when the power is supplied by the 5VDC jack on the board.
