I would like to ask, whether someone could recommend a decent high-density connector. I would need at least 12 lines (GND, +3.3V, 12V, I2C, plus 6 general-purpose I/O lines) in a small form-factor. My criteria are the following:
1. Small footprint (10, max. 15 mm in width)
2. Cheap (I need something like 1000 pieces, so even a couple of dollars would make a huge difference)
3. Standard, so that inexpensive matching cables can be found.
USB-C would be perfect, except that I have recently learned that in USB-C, either not all braids are implemented, or there is a chip that assumes that the device using the cable is intelligent, and is capable of negotiating current consumption, protocol, etc. I need a simple pass-through cable without any gimmick.
In any case, I would appreciate any hints.
