Questions
How big is the MicLed PCB?
It measures 44 × 0.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MicLed use?
8 parts, built around the ATTINY85V-10PU. 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 MicLed KiCad files?
From the gokul-rm/PCB repository on GitHub, at the commit this page was made from: the board is ledMic/micLed.kicad_pcb and its schematic DLC/DLC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicLed design in my own project?
Its repository states no licence, so its author keeps all rights: ask gokul-rm before reusing the design.
