Questions
How big is the Pepper PCB?
It measures 73 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pepper use?
52 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3, MBR0530 and BSS138. 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 Pepper KiCad files?
From the TheEvilRoot/pepper repository on GitHub, at the commit this page was made from: the board is pepper.kicad_pcb and its schematic audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pepper design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheEvilRoot before reusing the design.
