Questions
How big is the Linear regulator v1 PCB?
It measures 93 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Linear regulator v1 use?
38 parts, built around the LM7812 and LM7912T. 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 Linear regulator v1 KiCad files?
From the 57maker/linear_regulator_v1 repository on GitHub, at the commit this page was made from: the board is linear_regulator_v1.kicad_pcb and its schematic linear_regulator_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Linear regulator v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 57maker before reusing the design.
