7.0 BeagleBoard Hookup
This section provides an overview of all of the connectors on the BeagleBoard.
7.1 Connecting USB OTG
The USB OTG port connects to the PC host and uses a miniAB cable through which
power can be provided to the BeagleBoard. Figure 5 shows where the cable is connected
to the BeagleBoard.
If the OTG Port is to be used as a Host, the ID pin must be grounded. This means that
you must have a 5 pin cable connected to the OTG port on the BeagleBoard and you must
use a USB powered HUB. There is also an option to ground the ID on the board and is
discussed later. You can power the board form this port, but there may not be enough
power supplied by the PC to power all features, such as the USB Host ports and the
Ethernet Port. If you use the double ended USB cable, you should be able to power the
board with minimal issues as long as you do not load down the USB Host ports with
heavy current devices.
