Questions
How big is the RasPi HAT PCB?
It measures 65 × 56.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RasPi HAT use?
46 parts, built around the LM2596S-5.0, SMAJ40CA and SS16. 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 RasPi HAT KiCad files?
From the OpenKNX/OpenKNX-RasPi-HAT repository on GitHub, at the commit this page was made from: the board is hardware/EDA-Files/RasPi-HAT/RasPi-HAT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RasPi HAT design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenKNX before reusing the design.
