Just a simple sled that mount for a BeaglBone and a 400-point breadboard that's pretty useful for quick prototyping with the BeagleBone.
Sleds are 1/8" acrylic. Cut the black lines and etch the red. Assembly is a snap, just bolt the beaglebone on and stick your bumpers and breadboard on, but watch out for R150 and R189 when bolting the BeagleBone to the sled!
