Overview
Blinky Board is an open-source printed circuit board by A41K, from the A41K/Blinky-Board repository on GitHub. It is a 2-layer board of 73.7 × 71 mm with 38 parts on 19 nets, routed with 202 tracks and 7 vias.
It is built around the NE555P. Its parts include 10 diodes, 2 capacitors, 2 resistors, 2 ICs and 2 connectors.
Main components
1README
README.mdYeah so this is my blinky board for stasis. I actually made this because I really liked the Macropad and how you actually got the stuff from HQ to build it and also I actually wanted to jump back into stasis because I started before, but I had other YSWS's on my table.
Th guide was really easy and on point so it wasnt a challenge

Questions
How big is the Blinky Board PCB?
It measures 73.7 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blinky Board use?
38 parts, built around the NE555P. 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 Blinky Board KiCad files?
From the A41K/Blinky-Board repository on GitHub, at the commit this page was made from: the board is Board/Board.kicad_pcb and its schematic Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinky Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask A41K before reusing the design.
