Questions
How big is the Ecc88-test setup PCB?
It measures 70.6 × 67.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ecc88-test setup use?
35 parts. 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 Ecc88-test setup KiCad files?
From the schenkmi/electronic-projects repository on GitHub, at the commit this page was made from: the board is tube-testers/ecc88/kicad/v3/ecc88-test-setup.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ecc88-test setup design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
