Questions
How big is the FabRecorder PCB?
It measures 28 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FabRecorder use?
36 parts, built around the CD74HC4050M and LP2981-33DBVTE4. 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 FabRecorder KiCad files?
From the FabLabValsamoggia/FabRecorder repository on GitHub, at the commit this page was made from: the board is schemes/v0.00/fab_recorder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FabRecorder design in my own project?
Its repository states no licence, so its author keeps all rights: ask FabLabValsamoggia before reusing the design.
