Questions

How big is the Bureau detude3 PCB?

It measures 68.5 × 57 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Bureau detude3 use?

7 parts, built around the 1N4148W. 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 Bureau detude3 KiCad files?

From the HoraEmbedded/Projets_GSEAs repository on GitHub, at the commit this page was made from: the board is 03_Conception_PCB/driver-relais-nmos/Hardware/Bureau_detude3.kicad_pcb and its schematic 03_Conception_PCB/driver-relais-nmos/Hardware/Bureau_detude3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Bureau detude3 design in my own project?

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