Questions
How big is the Led tester PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led tester use?
30 parts, built around the LM321. 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 Led tester KiCad files?
From the HarkonenBade/led_tester repository on GitHub, at the commit this page was made from: the board is led-tester.kicad_pcb and its schematic led-tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led tester design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
