Questions
How big is the 8leds PCB?
It measures 65 × 41.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 8leds use?
40 parts, built around the LM1117-5.0, IRLML2502 and SS14. 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 8leds KiCad files?
From the eddyem/STM8_samples repository on GitHub, at the commit this page was made from: the board is LEDS_BT/kicad/8leds.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 8leds design in my own project?
Its repository states no licence, so its author keeps all rights: ask eddyem before reusing the design.
