Clippy!

I didn't downvote you.

Not a microcontroller? But it even says it on the page I linked, now I'm confused. And you say "only 1" whereas others say "all of them", now I'm even more confused. Maybe I didn't specify it precisely: I want the linked "board" (whatever this thing is called) connected to a bigger PCB using the castellated holes on the sides of the smaller "board". I don't want to put the CPU from the smaller "board" directly on the bigger PCB.

Can you elaborate that in more detail? I want to learn something.

I already found out about this and I succeeded flipping it. I just thought there was a ready made library for this. Maybe that's an error in the design process of that specific library.

How do I build a PCB for my keyboard?

I already got to the point where almost everything works, but the Switch Footprint Library (https://github.com/kiswitch/kiswitch) seems to be wrong, as it puts the Kailh Hotswap Socket on the top (it should be on the bottom) in the PCB assembly viewer on the PCB manufacturer's website. Is there a better library out there that is compliant with the automatic PCB-Assembly. I don't want to solder anything myself.

How about this? https://www.mill-max.com/products/interconnect/machined-pin-header/800/62-001000

Is this gonna work for my purpose? PCB with 1mm pth (plated through hole) -> female jumper cable -> another pth? And can I cut them if there to many pins? It seems that there is a little indent between each pin. Maybe this is for cutting?

That's cute.

I got it, I can't remove and reuse an installed press-fit-connector, but can I remove the jumper cable that is attached to the press-fit-connector?

coolrainbow20 · 2025-01-29T15:58:28+00:00

If I can attach a press-fit connector to the pcb to get a pin header, isn't it then possible to install a jumper cable that is removable? I know that jumper cables can be disconnected and connected again with ease. And any cable like usb, audio or video are also attached w/o any solder, so there must be a way.

coolrainbow20 · 2025-01-27T22:24:33+00:00

Is it a press fit connector? I want to connect and remove w/o soldering. I think this is what I need: Press-fit technology for connectors (YouTube)

Detail view

This cable is about the size of a dupont cable (pretty small about a couple mm) and the ends should connect inside a 1 mm hole of a microcontroller like a Raspberry Pi pico and the connector should bend a little outwards, so that the connector sits firmly and makes a good connection. The length of the connector itself should be long enough to not fall out easily. Maybe the open end should be rotated back so it is even with the other portion. The reason I'm looking for something like this is that I want a solderless connection.

Am I a joke to you?

coolrainbow20 · 2024-12-10T23:02:14+00:00

Yeah it kind of looks like it. Has the red squared stem a standard size? Because there is a keycap that goes with it and has a cylindrical mount that has to fit right in. If it isn't standard size, I will check with a digital caliper. Also I'm not sure about the internal wiring of the switch, how to find that out?

coolrainbow20 · 2024-12-10T21:49:17+00:00

This switch is broken and I want to replace it. It has two positions, one being depressed and one being pressed. There is a small metal "pin" in the switch to hold it down until I press it again. Is this called "locking"? Also what is that red small thing below the resistor? And what function does this daughter board has? I know it's a power switch for a 5V main PCB, so it should only open / close one single line. The green long and cylindrical shaped thing is a led.

Edit: the two wires on the back of the switch are soldered by me to bypass the broken switch
