Questions
How big is the A500 RGBtoHDMI PCB?
It measures 80 × 29.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the A500 RGBtoHDMI use?
19 parts, built around the LM1117-3.3. 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 A500 RGBtoHDMI KiCad files?
From the jbilander/A500_RGBtoHDMI repository on GitHub, at the commit this page was made from: the board is KiCad/A500_RGBtoHDMI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the A500 RGBtoHDMI design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
