Questions
How big is the RGB SCART BREAKOUT PCB?
It measures 87.7 × 45.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RGB SCART BREAKOUT use?
46 parts, built around the BC847 and MF-PSMF050X-2. 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 RGB SCART BREAKOUT KiCad files?
From the proboterror/RGB_SCART_S-Video_Breakout repository on GitHub, at the commit this page was made from: the board is KiCad/RGB SCART BREAKOUT.kicad_pcb and its schematic KiCad/RGB SCART BREAKOUT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RGB SCART BREAKOUT design in my own project?
Its repository states no licence, so its author keeps all rights: ask proboterror before reusing the design.
