Questions
How big is the HW15 PCB?
It measures 58 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HW15 use?
11 parts, built around the MT3608L. 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 eatmelonnnn/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 eatmelonnnn before reusing the design.
