Questions
How big is the CleanLVSupply PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the CleanLVSupply use?
81 parts, built around the TPS7A470X, LM25576MH, LMR54406FDBV and LMR64010XMF. 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 CleanLVSupply KiCad files?
From the BlockWorker/ModularAudio repository on GitHub, at the commit this page was made from: the board is CleanLVSupply/CleanLVSupply.kicad_pcb and its schematic 12VLDO/12VLDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CleanLVSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask BlockWorker before reusing the design.
