Questions

How big is the Medivault PCB?

It measures 98.5 × 47 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Medivault use?

32 parts, built around the ESP32-WROOM-32E, DHT22, AP2112K-3.3 and DS3231SN#T&R. 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 Medivault KiCad files?

From the chislonljoseph/Medivault repository on GitHub, at the commit this page was made from: the board is Hardware/Medivault.kicad_pcb and its schematic Hardware/Medivault.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Medivault design in my own project?

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