Questions
How big is the E Fidget Lite PCB?
It measures 16.8 × 13.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E Fidget Lite use?
11 parts, built around the ATTINY13A-SSU, BU2032-1, EE2-3NU and MMBT3904. 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 E Fidget Lite KiCad files?
From the miameows/E-Fidget-Lite repository on GitHub, at the commit this page was made from: the board is E-Fidget-Lite.kicad_pcb and its schematic E-Fidget-Lite.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E Fidget Lite 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).
