We support all Raspberry Pi 4 and the Raspberry Zero2. (You can solder the Zero2 directly to the board to get a very reliable connection) If you want to use an older Raspberry Pi 3 it is possible, there is an extra image available, but without some features and no updates.
You can find our open source 3D printable designs on our thingiverse page.
Our software und system is focused on the Raspberry Pi hardware. We also added a Wemos footprint, so you can use some features with a wemos esp32/8266 too.
