Questions
How big is the 12VLDO PCB?
It measures 32.1 × 9.1 mm and has 2 copper layers, 0.8 mm thick.
What parts does the 12VLDO use?
13 parts, built around the TPS7A470X. 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 12VLDO KiCad files?
From the BlockWorker/ModularAudio repository on GitHub, at the commit this page was made from: the board is 12VLDO/12VLDO.kicad_pcb and its schematic 12VLDO/12VLDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 12VLDO design in my own project?
Its repository states no licence, so its author keeps all rights: ask BlockWorker before reusing the design.
