I do have some wireless builds available already.

It’s okay, but I prefer the ts100. The pinecil is a bit unresponsive in waking up from idle.

Optimized for travel, then I’d suggest wireless low profile corne. It’s small, light and wireless.

Yep, wired keyboard uses QMK, wireless uses ZMK.

1000mAh, from my personal use, It can last at least 1 month possibly two, but I usually charge it once per 2-3 weeks.

Functionally, they’re not very different. The CZ has onboard controllers so over all, it’s thinners, it has a e-ink display so it burn less battery. The Corne uses separate wireless controller (bluemicro840), so I have to design a case around this controller, thus making the case thicker and less refined than the CZ. It also can use an e-ink screen (the nice!view), but it’s not very easy to find, so I stick with OLED screens. My version can accommodate a huge battery so it can last months event with OLED screens.

This is based on the v3 pcb, I’m not sure about the v2 pcb, I’ll have to check, but if the holes are 1-2mm from the controller, it will fit.

If you’re ready to loose the oled screens, then yes it should fit. I designed this for the choc version, and on the choc version, the holes for the oled is a bit closer to the promicro than on the cherry version. And if you install the cherry pcb on this, the oled holes are obstructed by a piece of the case, thus cannot fit properly. If you loose the oled screens, they should fit nicely.

I myself is a fan of trackball and we’re developing a wireless build with trackball.

actually when I post this, there is a field for url and I’ve filled that with the actual url for the store, somehow it doesn’t appear at all.
