This pegboard is 192 mm x 128 mm (7.6" x 5") large which is a bit smaller than half letter size and made from clear 1/8" thick acrylic. Additionally, you will receive four M4x20 mm long hex spacers made from nylon and four M4 matching nylon screws. These spacers function as feet for the board.
The board has 230 holes to accept our spring contacts and it can be mechanically linked to Lego bricks and Lego technic components. In the Lego raster, it is 16 x 24 large. Its shorter side is exactly half the length of a Lego baseplate which is 32 x 32.
