I’ve been working on shrinking the 21MB Manjaro kernel, mostly by disabling drivers for hardware you can’t easily install on a PBP, and once I’ve figured that all out I’ll put that up on the wiki.
However, that made me think about the plethora of little I2C sensors - IMUs, GPS, pressure, light - that are available now.
Stemma QT (https://learn.adafruit.com/introducing-a...-stemma-qt) is a 4-pin JST SH (1.0mm pitch) connector, which exposes I2C. It’s possible to level-shift it so that one can safely plug in 5v and 3.3v hardware.
Putting one (or two, with one poking out a new hole in the case) on the audio daughtercard would allow the solderless addition of pretty much any I2C hardware, and thus increases the hackability of the PineBook Pro . . .
I’d buy a new audio daughterboard to add this functionality, because while I could trace the I2C bus and tap it it would be a pain and fragile. Having a proper connector makes adding a sensor or two almost easy, instead of terribly daunting.
