Questions
How big is the LifeSequencer PCB?
It measures 972.2 × 655 mm and has 4 copper layers, 1.61 mm thick.
What parts does the LifeSequencer use?
569 parts, built around the SN74HC08D, ALQ305 and BC817. 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 LifeSequencer KiCad files?
From the acastles91/lifeSequencer repository on GitHub, at the commit this page was made from: the board is JL/JL.kicad_pcb and its schematic JL/JL-backups/JL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LifeSequencer design in my own project?
Its repository states no licence, so its author keeps all rights: ask acastles91 before reusing the design.
