Questions
How big is the Charger PCB?
It measures 115.1 × 70.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Charger use?
31 parts, built around the TL494, IRFZ44N and UF4002. 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 Charger KiCad files?
From the src94/Adjustable-Power-Supply repository on GitHub, at the commit this page was made from: the board is Charger/Charger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Charger design in my own project?
Its repository states no licence, so its author keeps all rights: ask src94 before reusing the design.
