Questions
How big is the ESP32 Robo Dev Board PCB?
It measures 60 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32 Robo Dev Board use?
72 parts, built around the ESP32-S3-WROOM-1-N8, STSPIN250, TCA9548ARGER and AP2112K-3.3. 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 ESP32 Robo Dev Board KiCad files?
From the Amoskeag/RoboDojo repository on GitHub, at the commit this page was made from: the board is Hardware/ESP32 Robo Dev Board.kicad_pcb and its schematic Hardware/ESP32 Robo Dev Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Robo Dev Board design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
