sweep36 VS zmk-urchin

there is the sweep (https://github.com/davidphilipbarr/Sweep). Also there are some sweep variants with 36 keys (https://github.com/sadekbaroudi/sweep36)

At the time I liked the sweep but there was no 36 option until /u/sadekbaroudi created one: https://github.com/sadekbaroudi/sweep36

With 36 keys you don’t need another controller, just use more pins of elite-c or nice nano. Here is an example of boards with 36 keys without using diodes: https://github.com/sadekbaroudi/sweep36

Take a look at the swweeep case, as I took this exact approach: https://github.com/sadekbaroudi/sweep36/tree/master/cases/swweeep

https://github.com/sadekbaroudi/sweep36 - this derivative of the sweep adds a 3rd thumb key and perkey LEDs to some of his versions.

I want to build a swweeep, a wireless 36-keys variant of the sweep.

have you already picked up the board and parts? The Sweep36 has oled, rgb, 2 extra keys and remains diodeless due to using an elite-c controller which exposes 5 more GPIO.

I have been using this setup with a layout derived from seniply for over a year and I've been loving it.

My spacebar is not a dual function key, you can see my layout on github (scroll down for the diagram).

Yeah, I use it in zmk
