Questions
What parts does the Tld use?
8 parts, built around the IRFZ44N. 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 Tld KiCad files?
From the el-bart/mini repository on GitHub, at the commit this page was made from: the board is test_load_driver/tld.kicad_pcb and its schematic garden_LED_light_RE/LED_lamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tld 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).
