I believe there is a small errata on the Mounting_Hole_Locations page.
At the bottom it states... "Standoff: McMaster Carr PN - 91115A510" ... This is not an actual part number in McMaster.
I think the last two numbers where switched and it should read... "Standoff: McMaster Carr PN - 91115A501"
Part number 91115A501 is a 3/8" size standoff (1/8" tall, 4-40, hex). The one on the deb board I have is 1/4" size, which is part number 91115A160.
