Questions
How big is the Zelvicka PCB?
It measures 102 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Zelvicka use?
214 parts, built around the ESP32-S3-WROOM-1-N8, CH340X, DRV8833PW and MT3608. 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 Zelvicka KiCad files?
From the RoboticsBrno/Robutek repository on GitHub, at the commit this page was made from: the board is hw/Zelvicka.kicad_pcb and its schematic hw/Conectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zelvicka design in my own project?
Its repository states no licence, so its author keeps all rights: ask RoboticsBrno before reusing the design.
