Another single-switch circuit board

[kiltannen]

I have used the Amoeba King PCB to create a dactyl manuform with SK6812MINI-E on every switch.

Any chance you could share some pics?

Sorry for the dumb question, I've been following this thread for a while now as a lurker. I wanted to order some of these and not sure which is the latest and greatest version?
Is it the one from mtl, jking or HID Tech?

https://github.com/mtl/keyboard-pcbs
https://github.com/JKing-B16/keyboard-pcbs
https://github.com/HID-Technologies/

and is king the best or royale?
Guess I'm just looking for most features/least problems.

Thanks in advance!

Hello ping,

I can't speak for the other links but here's my feedback on the HID Tech ones that I made.

The sole purpose of the 1u hotswap MX is to be easy to use - only two row connections, and two column connections.

I made them because I found the amoebas too "messy" if that makes sense.

I hope this helps.

That was helpful, thank you for your response.

You can find them on the Github: https://github.com/HID-Technologies/
There's the kicad files, the gerbers (in the release section), and some information there.

Cheers

Out of curiosity was the Kompacted-1u-Hotswap-MX PCB in the HID-Technologies repository created with a nightly build of KiCad? I have the newest KiCad (5.1.8-0-10_14) and everytime I try to open "plate.kicad_pcb" in that repository I get an error that my KiCad isn't new enough and I need at least version "6/14/2020" which looks an awful like a nightly build version number.

Do I need a nightly build version of KiCad to open this?

Hi,

I am new to customized keyboards. I found these switches via google search.

I am confused if I can use one of the amoeba pcbs for a build with rgb leds and NOT hotswappable.

Hope anybody can help me or can tell me other "mini pcbs" to use.

Thx in advance

Hi,

First - idk if that kind of "advertisement" (I guess) is allowed, so anyone let me know and I'll be happy to modify/delete.

You can use rgb amoebas, then you will have to connect vcc, gnd, and Din/Dout to each amoeba.
It's totally doable, just takes an insane amount of time and cables. If you google it you can find people who did it.

Otherwise, if you're doing a Dactyl Manuform Mini, you can take a look at HIDTech (our) 's flexil PCBs, we have an option with per-key RGB and no hotswap. You get one big PCB instead of many small ones. Only 4x6 and no 2 bottom keys though. Also the thumb cluster is only compatible with the DM Mini. It's also available in the full Bastyl Kit.

Cheers,

Thx for the answer, I think I need a own post for my topic.

I've made some updates that hopefully improve the design. In this revision, redundant column pads were added to the top and bottom. (Thanks, Lolligagger!) Also, pins were added to support both left-to-right and right-to-left LED data flows across a row. This will allow for the LED to always be mounted in the same orientation, which will simplify assembly and should reduce the possibility for wiring errors. Finally, the pins for data-out on the top and data-in on the bottom were removed. This removes some flexibility but seemed to be the right compromise.

Dimensions are 18.8 mm wide by 18.3 mm high.

I hope to create a wiring diagram to show how these would be connected in a matrix.

I will use your version for my project.

Can you tell me which leds I have to order?

https://keycapsss.com/keyboard-parts/pa ... gb-led?c=6
https://keycapsss.com/keyboard-parts/pa ... md-led?c=6

They have both the same name and I really dont know which fits.

Thx in advance

if I may make a suggestion, the pcbs are great, but it might make sense to make the column and row connection pads larger, so that you can solder to them without putting the wire through the hole.

The ones you want are the SK6812 Mini 3535 (https://keycapsss.com/keyboard-parts/pa ... gb-led?c=6). If you take a look at the pinout on that website it matches the pinout on the amoeba-royale PCB (rotate the pinout on the website by 180°)

If you take a look at the pinout of the mini-e ones the pinout doesn't match.

Saying that though I ordered some SK6812 Mini 3535 and they fall straight through the hole on the royale. So either JLCPCB didn't drill the holes accurately or the LEDs I bought are on the small side.
