Today I wrote an image on a 16 GB card.
I downloaded “http://storage.ruuvi.com/ruuviberry_latest.zip”,
unpacked it as balenaEtcher couldn’t unpack it.
After I followed the instructions at image startup, as well as running sudo apt update
and sudo apt upgrade, it has been running on my P4 model B since at. 11.30.
After unpacking, the image is called “ruuviberry_2019_08_27_minimal.img”.
