Questions
How big is the Ezbot PCB?
It measures 24.5 × 89 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ezbot use?
81 parts, built around the ESP32-S3-WROOM-1-N8, TPS54620RHLR, 10S45SP and AMS1117-3.3. 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 Ezbot KiCad files?
From the yohandev/ezbot repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/motor_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ezbot design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
