Questions
How big is the Digital Interface PCB?
It measures 91 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digital Interface use?
33 parts. 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 Digital Interface 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/01_Digital-interface/Prototype_0THT/Digital_Interface/Digital_Interface.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 Digital Interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask juamorenogo before reusing the design.
