Questions
What parts does the Pollen controller pcb use?
20 parts, built around the AM2302, ULN2003 and PN2222A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pollen controller pcb KiCad files?
From the pollen-project/PollenController repository on GitHub, at the commit this page was made from: the board is pollen_controller_pcb/pollen_controller_pcb.kicad_pcb and its schematic pollen_controller_pcb/pollen_controller_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pollen controller pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask pollen-project before reusing the design.
