Questions

How big is the Passboard PCB?

It measures 85.6 × 54 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Passboard use?

10 parts, built around the ESP32-C3, RP2040 and NT3H1101W0FHKH. 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 Passboard KiCad files?

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

Can I use the Passboard design in my own project?

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