 ====== Test jig for castellated pin module ======
-We had the need to test a custom module that came back from assembly. The module is meant to be soldered onto another PCB via castellated pins and is very small.

-As holding a multimeter probe (even if its a PCBite) would be a nightmare for more than one piece, I designed a little test jig that uses 0.7mm (!) pogo pins ([[https://www.distrelec.ch/de/federkontakt-16-mm-rundkopf-ptr-hartmann-1007-7n-au-49/p/30019672?track=true&no-cache=true&marketingPopup=false|MPN: 1007-D-0.7N-AU-0.49]]). The pogo pin holder is 3d printed with the 0.4mm standard nozzle diameter and surprisingly comes out well. Even if it's hitting the resolution limit of the Prusa.
