Questions
How big is the Coaster PCB?
It measures 198 × 98 mm and has 11 copper layers, 1.6 mm thick.
What parts does the Coaster use?
140 parts, built around the ESP32-PICO-MINI-02-N8R2, LMR16006XDDCR, TX1812Z5 and RC0603FR-100KL. 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 Coaster KiCad files?
From the evansj/ESP32-LED repository on GitHub, at the commit this page was made from: the board is PCB/Coaster/Coaster.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Coaster 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).
