Description
This is a pogo pin adaptor for boards that uses dual castellation for surface mounted modules.
It takes advantage and requires the use of cutouts under the modules as an alignment for the pogo pin positioning and the 3d printed retention clips.
I have not bothered to make this parametric. But can do if requested. This was created to solve a specific problem I had.
You may be interested in that I took around 10 revisions before getting the final 11th revision that I liked best.
Once printed, you need to insert the pogo pins in, then insert the modules on top and solder the modules to the pogo pins legs.
Do note you will need to do a test print first, because this design requires tight tolerance and thus this may differ between printers. But once dialed in, the print is repeatable.
Rev1 : First real release. Clips well and is designed for a module with only two castellations.
This is specifically designed not to require infills, and was printed on a 0.8mm nozzle at 0.2mm layer height. Took 54 minutes to print.
Also this requires accurate z axis calibration. You can use https://www.thingiverse.com/thing:3113686 to check.
Since I have not made this parametric, unless you are willing to manually adjust the openscad design files... these are the specs I have done this in.
Spec of the probe pins
first probe spacing from bottom of module : 3mm
Tried different clip design. The best is often the simplest. I tried other designs to try and add bit of kerning to reduce the springyness, but found that I could easily just reduce the springyness to a manageable level by cutting holes on the clip. Thus the more reliable and straightforward clip design similar to revision 1 was chosen.
