4.0 BeagleBoard Overview
The BeagleBoard is designed specifically to address the Open Source Community. It has
been equipped with a minimum set of features to allow the user to experience the power
of the processor and is not intended as a full development platform as many of the
features and interfaces supplied by the processor are not accessible from the
BeagleBoard. By utilizing standard interfaces, the BeagleBoard is highly extensible to
add many features and interfaces. It is not intended for use in end products. All of the
design information is freely available and can be used as the basis for a product.
BeagleBoards will not be sold for use in any product as this hampers the ability to get the
boards to as many community members as possible and to grow the community.
