Questions
How big is the Hal2137 PCB?
It measures 21 × 12.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hal2137 use?
8 parts. 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 Hal2137 KiCad files?
From the cr1tbit/hal2137 repository on GitHub, at the commit this page was made from: the board is hal2137.kicad_pcb and its schematic hal2137.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hal2137 design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
