FlexyPin - Pack of 100

by Solder Party

FlexyPin allows for easy insertion and removal of modules with castellated edges without the need for soldering!

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.

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

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

These pins have been a revelation and make mounting carrier boards like ESP32 or Pico a breeze. I have used them so far on pre-designed FlexyPin adapter boards but can see how easy it is to produce my own custom one. They are a bit fiddly to insert and line up but it becomes easier with practice.

Given 5 stars. I know they are quite expensive, However, when I received them I only got 94 in the pack. I contacted customer service to let them know and they just sent out another batch without any questions or me asking, hence the 5 stars. I did count the second batch and there were only 99 in it. I can't complain as I got more than what I paid for anyway, So win-win.

Previous order pack had 103 pins, recent order only 94 pins (ouch). For something relatively pricey (but undoubtedly useful) I would have thought 'at least 100 by weight'.

FlexiPins are tiny and designed to be used with FlexiPin adapters such as the Pico to Uno adapter which mounts a Pico on an Uno footprint boards. You need tweezers or forceps, an illuminated magnifying glass and, if possible, a circuit board holder to locate them in the board before soldering. Instructions are sketchy. For example, the FlexiPin YouTube video shows a board with one pin hole and a slot, while the Uno board has two holes on either side of a slot.

So £6 for 100 pins is a rip off. You should get the flexy pins with the adapter rather than separately. I hate the fact that this company splits up kits to make you pay more money. I doubt I will be buying from this company again. The prices are astronomical. Just can’t afford to buy here anymore.

Great spring pins - ideal for temporary connection to castellated boards such as Pi Pico etc. Quite tricky to solder though because of their small size !

These work GREAT. I use "bare" ESP modules at work, and sometimes I need to debug the stuff...
