Questions
How big is the CTA control board PCB?
It measures 252 × 152 mm and has 4 copper layers, 4.69 mm thick.
What parts does the CTA control board use?
619 parts, built around the NCS2325D, LM2904, MAX31855KASA+T and TCMT1100. 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 CTA control board KiCad files?
From the PySpice-org/eda-rw repository on GitHub, at the commit this page was made from: the board is kicad-examples/electrolab-cta-control-board/CTA_control_board.kicad_pcb and its schematic kicad-examples/capacitive-half-wave-rectification-pre-zener/capacitive-half-wave-rectification-pre-zener.unordered.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CTA control board design in my own project?
Its repository states no licence, so its author keeps all rights: ask PySpice-org before reusing the design.
