Questions
How big is the Launchpad PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Launchpad use?
175 parts, built around the ESP32-S3-WROOM-1-N8, LD39150DT33-R, USBLC6-2P6 and EMIF06-MSD02N16. 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 Launchpad KiCad files?
From the benjibst/launchpad repository on GitHub, at the commit this page was made from: the board is launchpad.kicad_pcb and its schematic audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Launchpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask benjibst before reusing the design.
