FlexyPin is a connector pin designed to be used with castellated modules with pitch down to 1.27mm.

It allows for easy insertion and removal of modules without the need for soldering.

FlexyPin works great for flashing/testing jigs and other use-cases where castellated modules are involved.


FlexyPins are gold-plated and keep their shape well. We haven't seen any issues over multiple (1000+) insert-remove cycles.

A 3D model as well as KiCad footprints and footprint reference drawing are available on our github.

A soldering guide is available here: https://www.youtube.com/watch?v=VZVIUo6SYR0

What you get

  • A pack of 100 FlexyPins Because the qty is measured by weight and not by count, the qty in the pack might slightly differ from a 100, in most of the cases it will be more than 100, but in a rare case it might be slightly fewer. Expected range is -5/+10

We also offer a selection of FlexyPin adapter boards for common modules in our store as well as longer pin headers that allow usage of FlexyPin boards with breadboards.
