BeagleBone DVI-D Cape

The BeagleBone Memory Expansion Cape provides BeagleBone the capability to add additional external memory devices. The External memory devices are interfaced via general purpose memory controller (GPMC) on the AM335x. Supported memory devices include NOR flash, NAND flash, or other memory devices that are asynchronous, synchronous, 8-bit or 16-bit.

Note: The BeagleBone Memory Expansion Cape only provides memory expansion capability for BeagleBone. It requires a memory module to work with BeagleBone.
