View Full Version : Hole Spacing

What is the hole spacing on the Propeller Proto Board USB? I've got some other components that I need to mount on that board and want to make sure that the pin / hole spacing is compatible.

0.1 inches

Hmmm. I don't see 0.1 inches anywhere in the spec for the adapter for my chip. It says it provides a 600-mils Adapter DIP-plug.

The spec is here: http://smt-adapter.biz/parts/S06-32QFN20-D6-SMT-S.shtml

Will that fit in to the Propeller Proto Board USB?

The 600 mils (i.e. 6 x 0.1") is the spacing between rows of pins. The pins themselves are virtually certain to be on 0.1" centers. It's such a cast-in-iron standard that it wouldn't make any sense to have done it another way. I can guarantee that the pins will line up with a 0.1" hole pattern.
