Questions
How big is the Delaycircuit3 PCB?
It measures 115.6 × 105.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Delaycircuit3 use?
21 parts, built around the CD4002BE, CD4001BE, NE555N and 1N4148WT. 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 Delaycircuit3 KiCad files?
From the agustinems/delayCircuitDigital repository on GitHub, at the commit this page was made from: the board is delaycircuit3.kicad_pcb and its schematic delaycircuit3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Delaycircuit3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask agustinems before reusing the design.
