　　The BeagleBoard is an OMAP3530 platform 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 OMAP3530 and is not intended as a full development platform as many of the features and interfaces supplied by the OMAP3530 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.
