dactyl-manuform VS Elite-C-holder

This has the 4th key and then a couple more https://github.com/jchendy/dactyl-manuform

idk if it counts because I don't think anybody other than me has built one, but feel free to add https://github.com/jchendy/dactyl-manuform/

Dactylria - a Dactyl ManuForm fork with thumbs inspired by Kyria and Keyboardio Model 01 by u/jchendy with source (git).

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 !

I just released the kicad files and gerbers for my Elite-C holder PCB
