The last talks they gave mentioned it is controlled via Bluetooth. So any Bluetooth capable device would be able to connect with it.

Current focus is to use the device as an input device for computers/phones.

This goes against the spirit of the back button. Back button should always take you to the last page you were on. Its always annoying when an app overrides that and instead takes you back to where it thinks you want to go.

With how cheap those chips are I’m not sure I see the value in sending it to the manufacturer.

I’ve also never seen a PCB that has the atmega built in show up without that already installed. If you want though you could find an open source board design you like and order the PCBs yourself without components… If you’re up for the challenge.

Still looking for alternatives for r/mechanicalkeyboards and r/spacex
