Questions
How big is the DCDC converter PCB?
It measures 102 × 128 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DCDC converter use?
379 parts, built around the MP2491CGQB. 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 DCDC converter KiCad files?
From the pureHK/LPV01_shield repository on GitHub, at the commit this page was made from: the board is DCDC_converter _panel/DCDC_converter.kicad_pcb and its schematic DCDC_converter _panel/DCDC_converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCDC converter design in my own project?
Its repository states no licence, so its author keeps all rights: ask pureHK before reusing the design.
