I am using this trick to convert the logic input to 5V, so that should work. Super hacky, but as far as I checked, every piece of this hack is entirely in spec for the components used.
I'll check with a simple Arduino program first I guess
UPDATE: Arduino program works, so it is not a hardware issue (lucky me)
26 WPM on first day is pretty solid.
I dropped from 70 to 15 when starting with an Ergodox and it took me about 10 days to get back to 60+
(And then I decided to switch to Colemak layout which is much harder than Row stagger -> column stagger I’d say)
