I’m working on a new split keyboard and woukd like to avoid soldering everything together. what are some connectors that can be used to connect things together?
My plan is to have a central unit with one controller, while still being able to dissasemble things etc.
I bought some usb-c male/females, but the males are a PITA to solder a diy 12-pin cable utilizing all pins for transfer, etc.
Using millmax sockets you could make your MCU hotswap, to be able to remove it and use it in another board. As suggested by another comment, hotswap sockets are also a good idea to avoid soldering switches.
What is it exactly that you don’t want to solder permanently to the board? Switches? Controller? Connector? Diodes? Screens? Rotary encoders?
I may be missing something here, but wouldn’t you still need to solder those connectors?
If you want to limit soldering as much as possible, I’d grab a BlackPill or similar that comes with pin connections that you could just plug into the pcb, and it would have enough pins that depending on how many switches you wanted you could probably get away without needing a matrix, so two less solder points per switch for each resistor. You could also probably benefit from hotswaps. While no reduction in solder points (still two per switch), it can be just a big lump of molten solder on each side - it doesn’t need to be quite so carefully done.
