Overview
ATtiny85-LEDs is an open-source printed circuit board by JeremySCook, from the JeremySCook/ATtiny85-5LEDPCB repository on GitHub. It is a 2-layer board of 37 × 40.5 mm with 15 parts on 14 nets, routed with 131 tracks and 10 vias.
It is built around the ATTINY85-20PU. Its parts include 5 resistors, 4 diodes, 2 switches, 1 capacitor and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.

wheel-light/README.mdKiCAD files for new version using SMD components that activates based on bike wheel's rotation.
Works, but could be improved. ICSP header is connected incorrectly, and battery life is somewhat unknown.

Questions
How big is the ATtiny85-LEDs PCB?
It measures 37 × 40.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATtiny85-LEDs use?
15 parts, built around the ATTINY85-20PU. 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 ATtiny85-LEDs KiCad files?
From the JeremySCook/ATtiny85-5LEDPCB repository on GitHub, at the commit this page was made from: the board is wheel-light/ATtiny85-LEDs.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATtiny85-LEDs design in my own project?
Its repository states no licence, so its author keeps all rights: ask JeremySCook before reusing the design.
