Skeleton-Dactyl-Mini VS Elite-C-holder

If you have access to a 3D printer, I would recommend handwiring a Skeletyl or Scylla.

if you are looking for a sculpted/keywell design I would start with something like the https://github.com/sanderboer/chonkybois or https://github.com/Bastardkb/Skeletyl then work on refining your needs from those ideas.

There's these made by Quentin, which can be mirrored for Skeletyl/Cnano.

Awesome. Do you think single-key RGB would be an issue? Would it add too many cables? I'm currently looking at the Skeletyl, but am intimidated by the four additional cables per LED.

If you have access to a 3d printer you could print something like a skeletyl or a dactyl manuform and then handwire it with some diodes and wires. That's the cheapest way I can think of.

I'd throw BastardKBs Keyboards into the mix as well as he's open sourcing all of his designs, for instance the Skeletyl or the Charybdis

You can take a look at the Skeletyl. It's a 5x3+3 design. Basically the upper three thumb keys of the one you posted and with 2 keys less on row 3 and 4.

The MCU is mounted on this breakout board: https://github.com/Bastardkb/Elite-C-holder. It provides a neat way to mount reset/power buttons and 3.5mm jacks for wired builds, as well as securing the MCU into the case. The matrix pins on the holder board are simply labeled as R1-5 and C1-6 for rows and columns presumably. I used a multimeter to figure out the corresponding pins on the nice!nano as following:

Hmm, it might depends on which controller holder you use. If you have the 2.0, then you can use this config: https://github.com/meln1k/zmk-config/tree/master/config/boards/shields/skeletyl_v2_elitec. If you use an older controller holder, then you need to change the pin assignments.

Hi ! So this is using the elite-C shield PCB, which the TBK also uses.

MCU: Elite-C with the shield pcb

Elite-C adapter PCB: for those who want to design their own Dactyl, this PCB has space for an elite-C, an audio jack, a reset button and two M4 screws - easy system to attach it to the case !
