    The (early run) 8-bit board I have here is an octagon 61 mm across each diameter.  Each edge appears to be ~ 25.5 mm, in other words edges might have been spec-ed at 1 inch.

    I have not measured the gold cup sensors that are parts of the kits, but typical molded cup sensors are about 9 mm diameter.

    thanks if possible would you be able to tell me the hole diameter and the distance between the side of the board and the side of the hole as well as the distance along that same edge between the approximate middle of the hole and the nearest corner. i'm trying to get the correct hole layout so that my fixture will be compatible.

    Hi Sky, 

    Again, this is an early run board I'm measuring so no guarantees that your board will be exactly the same.

    Hole diameter is ~ 4.7 mm (probably 3/16"), designed to snap into a nylon board spacer cylinder.  Which is supplied. Spacer stands the board 10 mm off the surface below.  Spacer inner diameter hole appears to be about 2.8 mm.

    Holes centers on one side are 13/16" apart.  Hole centers are 1/8" in from edge.

     thank you! if the rev updates i can just adjust the dimensions down the road but this should be great for the moment.
