Questions
How big is the Tv25-cpu PCB?
It measures 65.5 × 75.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tv25-cpu use?
49 parts, built around the ESP32-S3-WROOM-1-N8, XC6220B331MR and SK6812MINI-E. 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 Tv25-cpu KiCad files?
From the mirdej/tvtools repository on GitHub, at the commit this page was made from: the board is kicad/tv.controller2025/tv25-cpu/tv25-cpu.kicad_pcb and its schematic kicad/5port-headphone-belkin-clone-schnittplatz17./5port-headphone-belkin-clone-schnittplatz17.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tv25-cpu design in my own project?
Its repository states no licence, so its author keeps all rights: ask mirdej before reusing the design.
