Questions
How big is the Boost convertor PCB?
It measures 57.2 × 68.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Boost convertor use?
41 parts, built around the ATMEGA328P-AU, ADS1115IDGSR, MAX7219M and MC34063ECN. 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 convertor KiCad files?
From the kami-sona/Kicad_project repository on GitHub, at the commit this page was made from: the board is boost-convertor/boost-convertor.kicad_pcb and its schematic Converter_DC/Converter_DC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boost convertor design in my own project?
Its repository states no licence, so its author keeps all rights: ask kami-sona before reusing the design.
