I made this as Version 2 of my motor controller for my V8 Engine project, as that board failed to work entirely because of bad design.

Questions
How big is the Pollen PCB PCB?
It measures 115.5 × 82.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pollen PCB use?
30 parts, built around the DHT22, MMBT2222A and SI2319CDS. 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 PCB KiCad files?
From the pollen-project/data-collector-controller-PCB repository on GitHub, at the commit this page was made from: the board is Pollen PCB/Pollen PCB.kicad_pcb and its schematic KiCad-RP-Pico-main/Test/Test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pollen PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask pollen-project before reusing the design.
