I just put together my own Airgradient using a slightly tweaked version of the v2 basic DIY PCB. Thanks so much for sharing it with the community! It was great to have the flexibility to replace the BOM with silghtly a different microcontroller and temp sensor
Is it right to assume that Creative Commons BY-SA was picked over say GPL v2 or v3 because of the attribution requirement it adds beyond just being sharealike?
Also, props for not going with one of the non-commercial variants - the definition of commercial is so debatable, and I'm not sure if it's ever been enforced.
Yes, we do see so many positive contributions from the community - not only on the technical side but also for example environmental justice organisations that build workshop material for students on top of the kit. So we want to make sure that all contributors get attributed.
