Questions
How big is the Sequencer PCB?
It measures 77.9 × 161.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sequencer use?
122 parts. 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 Sequencer KiCad files?
From the DavenportEmma/sequencer repository on GitHub, at the commit this page was made from: the board is hardware/pcb/sequencer/sequencer.kicad_pcb and its schematic hardware/pcb/io/io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sequencer design in my own project?
Its repository states no licence, so its author keeps all rights: ask DavenportEmma before reusing the design.
