Several months ago we announced that there was the possibility we would have to switch our ARM microcontroller to a new chip. This was primarily due to the fact that the ST32 microcontrollers in our boards are very difficult to source at scale right now given the current state of the supply chain (I’m sure you’ve read a lot about the global chip shortages already). In the event we had to switch over the chip, this would have potentially resulted in a temporary loss of compatibility with QMK/VIA until we were able to complete the firmware development.
Fortunately, we have thus far been able to source enough ST32 chips to continue production with them for the foreseeable future. This has also fortunately given us plenty of time to finalize development of QMK/VIA compatibility for the new chip in the event we have to switch over sometime next year, so there should not be any loss of compatibility on production units.
So in summary, we no longer expect any outages of QMK/VIA compatibility in new boards.
