I wish to design two separate PCBs (due to mechanical requirements), with 4 interconnections in between them.
Now, I could use standard pin header males and females for this task:
However, PCBs distance is less than 2mm (!).
I couldn't find shorter pin headers, are they existing at all?
I need only 4 pins, and it two PCBs must remain detachable (soldering them together is not an option).
Is there any option for this which I can finetune the 2 PCBs distance at least with 0.5mm precision (but 0.25 or 0.2mm would be even better)
Two boards are needed to be stacked i.e. like a sandwich, one is the bottom board, other is the top board:
---------------- TOP board | | | | ---------------- BOTTOM board
4 connectors are used for USB (+5V, GND, D+, D-).
