Questions
What parts does the Spark use?
16 parts, built around the MBR120VLSFT1G-TP, PMBT2369, SRR1260-151K and STD2805T4. 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 Spark KiCad files?
From the zheylmun/charger repository on GitHub, at the commit this page was made from: the board is hardware/spark/spark.kicad_pcb and its schematic hardware/spark/spark.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spark design in my own project?
Its repository states no licence, so its author keeps all rights: ask zheylmun before reusing the design.
