Questions
How big is the HW15 PCB?
It measures 27.5 × 26.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HW15 use?
7 parts, built around the NE555D. 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 HW15 KiCad files?
From the finnpetrie/ME433 repository on GitHub, at the commit this page was made from: the board is HW15/HW15.kicad_pcb and its schematic HW15/HW15.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HW15 design in my own project?
Its repository states no licence, so its author keeps all rights: ask finnpetrie before reusing the design.
