This folder contains the KiCad project for the Addressable LED Delay Splitter PCB.
Production files
Production files can be found in the jlcpcb/production_files folder.
These files were generated by the KiCAD JLCPCB tools plugin.
It should be possible to upload the GERBER archive to other PCB manufacturers as well, but this has not been tested.
The BOM and CPL files are in the format required by JLCPCB.
It may be required to check and adjust the part numbers before ordering, because parts are from time to time replaced or go out of stock.

Questions
How big is the Addressable LED Delay Splitter PCB?
It measures 13.5 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Addressable LED Delay Splitter use?
19 parts, built around the ATTINY406-SN. 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 Addressable LED Delay Splitter KiCad files?
From the maiksicks/Addressable-LED-Delay-Splitter repository on GitHub, at the commit this page was made from: the board is kicad/Addressable_LED_Delay_Splitter/Addressable_LED_Delay_Splitter.kicad_pcb and its schematic kicad/Addressable_LED_Delay_Splitter/Addressable_LED_Delay_Splitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Addressable LED Delay Splitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask maiksicks before reusing the design.
