Questions
How big is the RestroBOT PCB?
It measures 85 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RestroBOT use?
24 parts, built around the ESP32-CAM, ESP32-WROOM-32E-N8R2, L293D and HC-SR04. 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 RestroBOT KiCad files?
From the PrashilLamichhane/RestroBOT_PCB repository on GitHub, at the commit this page was made from: the board is RestroBOT.kicad_pcb and its schematic RestroBOT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RestroBOT design in my own project?
Its repository states no licence, so its author keeps all rights: ask PrashilLamichhane before reusing the design.
