[Oshpark] HQ ProgKey - Universal Driver Programming Key

I guess with prog key I also will slowly migrate to qfn20 MCUs

the customer for the 10.25mm driver wants to use a flexible PCB key that gets glued to a sort of 3D printed part following the shape of the prog pads(in this case a circle),
so he can arrange the viases on the driver as he likes and make custom keys in any form and pin orientation

I think, if I remember correctly, when I introduced parts of this idea a while ago, that I suggested putting the pins into a 3-D printed housing.

Based on the original suggestion by TK, that was implemented in the D4S

Emisar D4S review

Well, the cat is out of the bag. Emisar has a new light called the D4S. It’s like an Emisar D4, but sized for a 26650 cell, throwier, and with some other misc improvements. It also has cyan-colored aux LEDs under the optic, 16 of them, which work a bit like tritium vials.

I was thinking square format, 1.27mm spacing. But anything else is possible with this approach.

Mike C seems to be pretty nifty with 3D printing …
