Questions
How big is the Flyback PCB 60Hz PCB?
It measures 174.2 × 124 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flyback PCB 60Hz use?
107 parts, built around the L7812CV, L7912CV, TL431ACLPR and SS14. 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 Flyback PCB 60Hz KiCad files?
From the juamorenogo/DCSource_DIY repository on GitHub, at the commit this page was made from: the board is Electronic-design/General-Design/PCB/03_Power-supply-Flyback/Flyback_PCB_60Hz/Flyback_PCB_60Hz.kicad_pcb and its schematic Electronic-design/General-Design/PCB/00_DC-DC-Converter/Flyback_PCB/Flyback_UCC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flyback PCB 60Hz design in my own project?
Its repository states no licence, so its author keeps all rights: ask juamorenogo before reusing the design.
