Questions
How big is the Lightbeam S3 PCB?
It measures 250 × 25 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Lightbeam S3 use?
73 parts, built around the ESP32-S3-WROOM-2-N32R8V, VEML7700-TT, AP2112K-3.3 and DS3231MZ+. 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 Lightbeam S3 KiCad files?
From the besser435/Lightbeam-S3 repository on GitHub, at the commit this page was made from: the board is lightbeam_s3_PCB/lightbeam_s3.kicad_pcb and its schematic lightbeam_s3_PCB/lightbeam_s3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightbeam S3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask besser435 before reusing the design.
