Questions
How big is the Stack light PCB?
It measures 188.5 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stack light use?
46 parts, built around the ESP32-S3-MINI-1U-N8, AZ1117CH-3.3TRG1, AZ1117CH-5.0TRG1 and SN74LVC1T45DBVRE4. 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 Stack light KiCad files?
From the CarterKoopa/stack_light_pcb repository on GitHub, at the commit this page was made from: the board is stack_light.kicad_pcb and its schematic stack_light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stack light design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
