Questions
How big is the Pirhat02a PCB?
It measures 34 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pirhat02a use?
18 parts, built around the 1N5819HW, BC817 and SMF24A. 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 Pirhat02a KiCad files?
From the onhala/pirhat repository on GitHub, at the commit this page was made from: the board is schematic_pcb/pirhat02a.kicad_pcb and its schematic schematic_pcb/pirhat02a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pirhat02a design in my own project?
Its repository states no licence, so its author keeps all rights: ask onhala before reusing the design.
