Yes, although yesterday we got some more information from @nrp which fills in a lot of the blanks on the hardware side, we still don’t know the exact I2C protocol to use (that’s software side). The bigger limitation is really just that very few people have hardware outside of Framework, so the mechanical part (how tall/wide/thick can the touchpad be) is uncertain. If you’ve got the machine in your hands you can take out a ruler and micrometer and work this out in relatively short order, so this will resolve itself in time, especially as batch 1 makes its way out into the world.
