Forked from @jincao1, only changed brightness from 128 to 255. Obviously this will adversely affect battery life.

I flashed this on my keyboard with QMK Toolbox in (Windows 11) and am typing this right now on it. So I guess it works, hopefully this helps someone else.

Strongly recommend you fork this or upstream and build yourself, but if you don't wanna mess with all of that, see the attached bin
