Questions
How big is the VRM Module PCB?
It measures 37 × 21.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VRM Module use?
15 parts, built around the TPS54429PWP. 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 VRM Module KiCad files?
From the OSHE-Github/Smart-BREAD repository on GitHub, at the commit this page was made from: the board is Loaf/PCB/5V4A VRM Module/VRM Module.kicad_pcb and its schematic Loaf/PCB/5V4A VRM Module/VRM Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VRM Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask OSHE-Github before reusing the design.
