Questions
How big is the Hakea fillets PCB?
It measures 155.2 × 127.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hakea fillets use?
111 parts, built around the AP2112K-3.3, TP4054, AO3401A and SR05. 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 Hakea fillets KiCad files?
From the vattern/hakea repository on GitHub, at the commit this page was made from: the board is hardware/PCB/hakea-fillets.kicad_pcb and its schematic hardware/PCB/hakea-fillets.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hakea fillets design in my own project?
Its repository states no licence, so its author keeps all rights: ask vattern before reusing the design.
