Questions
How big is the Astable Multivibrator PCB?
It measures 44 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Astable Multivibrator use?
13 parts, built around the BC547. 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 Astable Multivibrator KiCad files?
From the macmade/Electronics-Tutorials repository on GitHub, at the commit this page was made from: the board is Astable Multivibrator/Astable Multivibrator.kicad_pcb and its schematic Astable Multivibrator/Astable Multivibrator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Astable Multivibrator design in my own project?
Its repository states no licence, so its author keeps all rights: ask macmade before reusing the design.
