Questions
How big is the Boost sequencer PCB?
It measures 49 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Boost sequencer use?
56 parts, built around the ATTINY214-SSN, BC817, PMV65XPER and PMV130ENEAR. 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 Boost sequencer KiCad files?
From the danupp/boost_sequencer repository on GitHub, at the commit this page was made from: the board is kicad/boost_sequencer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boost sequencer design in my own project?
Its repository states no licence, so its author keeps all rights: ask danupp before reusing the design.
