Questions
How big is the Multivibrator PCB?
It measures 43 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Multivibrator use?
19 parts, built around the 2SC1815. 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 Multivibrator KiCad files?
From the HongoMCC/multivibrator repository on GitHub, at the commit this page was made from: the board is multivibrator.kicad_pcb and its schematic multivibrator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Multivibrator design in my own project?
Its repository states no licence, so its author keeps all rights: ask HongoMCC before reusing the design.
