The reason the teensy is used for advantages is that they use a bigger matrix than most keyboards, so they need more pins than the pro micro can provide. That being said, if you don't care about the caps lock lights you can use this pcb with an $11 teensy LC.
If you are an advanced user of the QMK firmware, note that despite QMK working on the Teensy 3.6, some features are not yet ported/working. As QMK was originally made for AVR micro controllers, you will likely find best overall QMK feature availability with the older Teensy++ 2.0.
2. Another addition would be to add USB hub-functionality? I wonder if that's hard/makes sense, but I really need it, e.g. for the IR receiver for the mouse -- although seldomly used, I need it when in skype/teams/zoom meetings, and other non-keyboard optimized programs.
3. Another, probably far fetched, but integrate mountable storage into it some how? (There's so much space in the Kinesis case). I have an extra M.2 NVMe lying around, I'd love to stick it in the Kinesis, and show it as a mounted device.
4. I wonder if somehow, one could do something crazy with integrating some functionality with a Pi Zero or similar? (not sure what, I'm just throwing out ideas)
@tinyenormous Good initiative! For group buy, maybe include components as well (but excluding teensy)?
EDIT: I notice Stapelberg mentions adding USB-hub as a cool potential project in his stream, 29 min in.
