Yeah I edited a comment above with that finding. I was on mobile and didn’t see the tab

Yeah I was looking at their assembly doc on my phone and saw it there, so just think they forgot it.

I’ll have to check out those Bosch sensors. I wanted to measure VOCs getting kicked off of resin 3D printers so was mostly just looking at full solution when I last looked.

EDIT: They responded on GitHub already. It’s listed in a separate tab of the BOM. So yeah, just an SPS30 and Bosch BME280

I’ll have to reach out to their team, but at the moment the Bill of Materials doesn’t appear to list an Air Quality sensor at all. So that’s confusing. I was interested because I’ve been wanted to measure VOCs in a manufacturing lab but that tech is still expensive.
