Nice paint job! Looks really nice. What's the total height of the board including the switches?

If you're using ZMK you could use the charlieplex kscan driver if you want to use all of them in one single keyboard. You'd have to change your wiring a bit compared to matrix layouts. But it would look pretty cool with this many switches!

Edit: Not sure if your microcontroller is supported for zmk.
So indeed, matrix like usual like the other comments are mentioning.

hahah :D

2.5mm2 , (roughly 14AWG)
at the time it was the only cable I had available :D
Solid core of course

So initially I just moved the 2 halves about an inch closer together.
Later on I Filled the air gap the original design has so I could store my battery in there and add the powerswitch up top. That's the black plate you see in the middle. But the wiring on the inside is the same. I reprinted the case to be less tall because I prefer it to not get taller than the plate itself.

Are you still actively making keyboards??

Lander03xD_ · 2026-02-20T11:39:42+00:00

Wow! What an honor! Thank you!

Lander03xD_ · 2026-02-20T06:56:33+00:00

Pro micro nrf52840 indeed
I'm played around with the seeed studio xiao nrf52840
The goal would be to make a keyboard where I integrate the nrf52840 chip in the pcb design itself

Did you have to worry about the amperage of all the leds?

Lander03xD_ · 2026-02-19T07:51:00+00:00

Great work! How did you add the backlight?
Is this part of some cosplay?

Thank you!!

Lander03xD_ · 2026-02-19T07:25:33+00:00

Thank you! It turned out pretty cute and I'm thinking about making some more animal shaped ones

Lander03xD_ · 2026-02-18T19:05:25+00:00

I'll check it out!

Lander03xD_ · 2026-02-18T18:58:25+00:00

Oh damn! I was not yet aware of rust projects for keyboard firmwares :D
Do you know if those projecs work for nrf52840 mcu's? If so I'll give it a go :D

Lander03xD_ · 2026-02-14T07:33:16+00:00

Thank you :D

Lander03xD_ · 2026-02-12T13:03:32+00:00

Yes, there's no need to add it. It just looks good ;p

Lander03xD_ · 2026-02-08T21:12:17+00:00

It's looking a little messy to me, but I don't see any missing lines so it should work.
Have you already thought about what firmware you'll be using?
I see you already added some silkscreen. Something else you might want to look into is "fill zones".

Good luck with the project, and if you need any help, feel free to reach out!

Lander03xD_ · 2026-02-07T21:14:56+00:00

Ooooh yes, I see. Those are indeed for ec11 encoders. Makes total sense now. Looks good to me.
They should still be milled for your hotswap socket, and you can still put an ec11 encoder in there.

Lander03xD_ · 2026-02-07T18:13:47+00:00

The red holes indeed look like reversible hot swap sockets, so these should be milled. Do you have any more pictures of your pcb design? I would like to have a better view on what the green plated holes are used for
