Questions
How big is the Lab Bench PSU PCB?
It measures 110 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab Bench PSU use?
84 parts, built around the LM2576T-ADJ, LM324, BC557 and BC547. 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 Lab Bench PSU KiCad files?
From the BojanSof/Lab-Bench-PSU repository on GitHub, at the commit this page was made from: the board is kicad/Lab-Bench-PSU.kicad_pcb and its schematic kicad/Lab-Bench-PSU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab Bench PSU design in my own project?
Its repository states no licence, so its author keeps all rights: ask BojanSof before reusing the design.
