I'm in the process of designing a tiny embedded system, it has quite a bit of sensors and it is controlled by 2 MCUs.
On previous versions of the test boards, I used 2mm pitch size headers for connecting the main board to a programming board. For the new version of the board, we definitely can not put these headers anymore.
I had the idea of using tiny 0.35 ~ 0.4 mm pitch connectors to interface both boards. I never tried to deal with this type of connectors before and I was wondering if they would be a good option for repetitive use, which will happen when programming and testing the device.
I've found the processes of connector hunting quite hard as there is a HUGE selection of parts and I cannot find the wire that I'm looking for. I think I may have to custom order a FPC wire too?
I’m wondering if anyone had a similar experience or suggest a different method for interfacing the boards?
