Hello forum,
I'm designing for my company a very-low-cost parallel (10 tap) programming tool for STM32F4 target.
The solution identified is an SBC with an isolated usb hub where 10 STLINK-V3MINIE are installed. Actually we've successfully tested this setup in lab, where 10 instances of STM32_Programmer_CLI.exe (pointing each one to one of the 10 different programmers' SNs) are launched via cmd.exe.
Every target board is fixtured to the assembly via a bed-of-nails and my actual difficulty is to connect each nails to STLINK-V3MINIE SWD lines: I can't solder directly the nails to the STDC14 cable since I should use the flat from IDC as pigtail and I don't like the ridiculous AWG and, for various reasons, I don't want to customize the STLINK-V3MINIE soldering, e.g., a female header to card-edge pads connector (as I did for my lab tool).
We're considering in using the board-to-board connector with is designed to use with the AVX 009159010061911 which is a board-to-board connector but I haven't find in the AVX catalog a compatible 2.00mm top+bottom wire-to-board (wire to card-edge) alternative that would enable the bed-of-nails cabling to reach a connector which I could easily remove from the programmer for maintenance.
Anyone have already find a solution for that?
Thanks in advance,
Luca

Well, that's another topic, and an endless one at that... which would surely leave the permitted bounds of this forum quickly.
But it supports my impression that the education of most business economists and the managerial class in general is often lacking the mathematical toolkit, rigor, and foresight.
Every decision has consequences, someday.
I would recommend to stash a few V3MINIEs, you might need them.
