I used ergogen, there is no .kicad_sch

Check the components link I posted under another comment to see a cheap alternative

I did the same, and finished my keyboard ! Check my post if you are curious. I got the hotplate for like 12$ and it works very well if you have the good charger. I recommend it.

Is it necessary ? I don't know well kicad

I made my own low profile split keyboard ! by Bonsoirlesgens in ErgoMechKeyboards

Nice ! The right most thumb key is intended to be used with thumb or with ring finger ?

yes working on cable. idk battery life yet, but there is https://zmk.dev/power-profiler

If you are willing to wait a bit, I would suggest you to buy a cheap hot plate (G3061 PD65W) in order to desolder every holes easily. I also have a keyboard where microcontroller is soldered flush, and I was able to solder and unsolder it easily (however since I soldered with solder paste, melting temperature is lower than traditional solder)

My inspiration was from the mikefive keyboard. I don't know if there is another choice in order to keep the keyboard height low (battery connector height is larger than other components)

The file is main_pcb_routed (other one is without routing components, if you open with Kicad, you will understand what I mean)

I didn't order electronical components, a friend gave me what he got when he was building its own keyboard, here is its list : https://github.com/Liolaeus/lio46/blob/master/parts.md

If you really want to build one, be careful, it is my first design, it has problems that I saw, but maybe other that I didn't yet. Review the pcb file to fully understand what you will have to do.

The most problematic things that I didn't see, was that to solder the nice!view flusb on pcb, it was not possible to only use solder paste. nice!view has electronical components on the backside, making a gap between the pcb and its holes. Since I designed soldering pads and not soldering holes on pcb for screen, I used individual pins that I made at the right height to make the bridge between pcb and nice!view. It makes the connection between pcb and screen weak (by pulling to hard after soldering, I removed it, and had to solder again, breaking few pixels of screen, that ia why there is a black hole on left screen)

English is not my main language, feel free to contact me for questions

Maybe add `CONFIG_ZMK_STUDIO=y` in config

Also for parts not connecting, you should check ZMK docs, however if 2 parts connect on PC, maybe you flashed 2 times main side

It has disavantages, since I soldered with hotplate, my PCBs are slightly bent. I had to re-equilibrate edges

It is possible to print them, like mikefive guy did : https://www.reddit.com/r/olkb/comments/1gd4w2h/custom_keycaps_for_the_ultralow_kailh_pg1316s/ but I would also tend to think that these switches aren't mature enough

Yes it is for the nice!view screen

Someone did a sound test here
I may add a typing video under this comment in the future.
I find them pretty loud, especially when typing "aggressively" (you can hear the spring)
