Standard cap for the LilyPad housing, for which more information can be found here
BASE IS NOT INCLUDED AND MUST BE ADDED TO SHOPPING CART SEPARATELY. See the link to the main product page above for more info.
This cap is enlarged to support mounting a 50mm breakout board (or second mainboard) on the underside. It increases the total height of the housing from 32mm (1.25") to 44mm (1.75"), and leaves 12mm clearance between the base-mounted board and the cap-mounted board and 9mm minimum clearance between the upper board and the ceiling.
NOTE ABOUT THIS BEING A PROTOTYPE/ALPHA VERSION OF THE HOUSING: The physical dimensions of the LilyPad are not terribly well documented and I don't have one in-hand to measure at the present time. The current dimensions were derived from the LilyPad EAGLE files as well as VERY CAREFUL rotoscoping of the photos from SparkFun's product pages, however - discretion being the better part of valor - I have intentionally left the board locating studs slightly undersized for this reason, so the boards might currently be a slightly loose fit.
