Questions
How big is the HDMI SWITCH PCB?
It measures 39 × 37 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HDMI SWITCH use?
20 parts, built around the TMDS261BPAG, 24LC024/P and AMS1117-3.3. 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 HDMI SWITCH KiCad files?
From the Az154za/HDMA_DUAL_SWITCHER repository on GitHub, at the commit this page was made from: the board is PCB/HDMI_SWITCH.kicad_pcb and its schematic PCB/HDMI_SWITCH.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HDMI SWITCH design in my own project?
Its repository states no licence, so its author keeps all rights: ask Az154za before reusing the design.
