Questions
How big is the ModularPSU PCB?
It measures 230.7 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ModularPSU use?
544 parts, built around the AP64060WU, PMPB11EN, BC857 and IRLML6401. 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 ModularPSU KiCad files?
From the dmanla/ModularPSU repository on GitHub, at the commit this page was made from: the board is ModularPSU/ModularPSU.kicad_pcb and its schematic ModularPSU/24V_BUCK_BOOST_TO_5V.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ModularPSU design in my own project?
Its repository states no licence, so its author keeps all rights: ask dmanla before reusing the design.
