Questions

How big is the Araneo mainboard PCB?

It measures 73.8 × 55.3 mm and has 4 copper layers, 1.61 mm thick.

What parts does the Araneo mainboard use?

116 parts, built around the MMC5983MA, PAM8403DR, BMI270 and BZT52B12. 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 Araneo mainboard KiCad files?

From the misadecki/araneo-project repository on GitHub, at the commit this page was made from: the board is electronics/araneo-mainboard/araneo-mainboard.kicad_pcb and its schematic electronics/araneo-mainboard/araneo-mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Araneo mainboard design in my own project?

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