Questions
How big is the SateLight Main PCB?
It measures 101.4 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SateLight Main use?
38 parts, built around the ESP32-WROOM-32, TLV75533PDBV, GG0603052R542P and 1N5819WS. 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 SateLight Main KiCad files?
From the ChrisMeletis/satelight_pcb repository on GitHub, at the commit this page was made from: the board is SateLight-Main/SateLight-Main.kicad_pcb and its schematic SateLight-LightSensor/SateLight-LightSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SateLight Main design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
