My daughter board was designed to fit existing holes on the Propeller Protoboard. Three of the five pin (holes) already have the correct Voltages/Signals present ( +3.3v, GND, and Xtal Input), only the two I2C lines will be jumpered as necessary.
Use of the very short Crystal Pin Socket will allow for a very low daughter board profile. In the past, I have used salvaged machined DIP socket/pins that stood up about 1/10 inch above the board, their hight make the daughter board a little wiggly.
|Crystal Socket - H3153-50|
I asked the folks at the Parallas Propeller Forum if anyone could provide the exact part number that was used in production. Several user suggestions were provided, and then with a lot of minuet specs comparing, I think I have found an acceptable part - I now have several on order.
Only receipt of the order will confirm. Note: the photo suggests the part is longer than its specs (perceived aspect ratio) . The part fits into a 1.0mm hole and its over all length is only 3.61mm. The Pin Socket accepts a 0.51mm wire pin, similar to those found on small crystals, at 0.47mm dia (measured).
This will be a great (but very small) part to be added to my collection, for this and future projects.
I enjoy chasing/tracking down "small and interesting" parts for my projects. I have blogged about many other parts in the past, maybe it is an expression, or a long lost need, of a "hunter/gatherer". I may make this a re-occurring theme on my blog - Part Quest.
