Questions
How big is the DDC CI Injector PCB?
It measures 49.1 × 35.5 mm and has 4 copper layers, 1.59 mm thick.
What parts does the DDC CI Injector use?
38 parts, built around the PCA9509DP, ESD224DQAR and PCA9641PWJ. 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 DDC CI Injector KiCad files?
From the AlexanderMandera/DDC-CI-Injector repository on GitHub, at the commit this page was made from: the board is DDC-CI-Injector.kicad_pcb and its schematic DDC-CI-Injector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DDC CI Injector design in my own project?
Its repository states no licence, so its author keeps all rights: ask AlexanderMandera before reusing the design.
