This is deigned for mounting the Arduino Hero and breadboard that came with the 30 Days Lost in Space adventure kit. You will need (3) #4x40 x 3/8" Machine Screws and matching nuts to attach the HERO.  You can use the adhesive backing on the back of the bread board or just friction-fit it. 
There is an optional lid with 28mm of internal clearance if you want to be able to  close things up but leave components plugged in.
