Questions

How big is the OpenHAK beta PCB?

It measures 38.1 × 25.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the OpenHAK beta use?

41 parts, built around the MAX30100EFD+, BMI160 and MCP73831. 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 OpenHAK beta KiCad files?

From the OpenHAK/OpenHAK_beta_hardware repository on GitHub, at the commit this page was made from: the board is KiCAD Files/OpenHAK_beta.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the OpenHAK beta design in my own project?

Its repository states no licence, so its author keeps all rights: ask OpenHAK before reusing the design.
