This is a high quality metal case to protect your BeagleBone Black. All cutouts are aligned accurately with the board, for example the microSD slot has very little clearance but the card can be inserted without touching the enclosure. This is not a sealed case, but provides small slits through which to view the various onboard status LED indicators. Knockouts are provided for a DB9 connector (9 pin serial / VGA) and a round pushbutton / indicator; the DB9 could be used for connection to internal IO pins (which provides a more finished look than an opening for a ribbon cable would). Drawings are available on the manufacturer's web site. Recommended for the "finished project" rather than active experimentation.
