Many keyboards use the qmk firmware these days, qmk.fm, which can be programmed with the Vial configurator, get.vial.today .

Here's one typical qwerty-ish layout for 42 keys: https://mark.stosberg.com/markstos-corne-3x5-1-keyboard-layo...

And for something more weird but still fully featured, Miryoku is a fairly common micro-keyboard layout, https://github.com/manna-harbour/miryoku .

Why? Well, I really admire Jonas Heitala's documentation of his journey to find a layout that fit his aesthetic: https://www.jonashietala.se/blog/2023/11/02/i_designed_my_ow... . My layout isn't as extreme, it's still qwerty-ish, but I've been heavily inspired by his thorough analysis.

Wireless keyboards (like the one linked) typically use ZMK instead to my knowledge. It's similar to QMK—so much of the knowledge still applies—but it isn't 1:1.
