Questions
How big is the PentaBlinky PCB?
It measures 40.6 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PentaBlinky use?
18 parts. 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 PentaBlinky KiCad files?
From the UserHackable/PenteBlinky repository on GitHub, at the commit this page was made from: the board is KiCad/PentaBlinky.kicad_pcb and its schematic KiCad/PentaBlinky.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PentaBlinky design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
