Questions
How big is the Logic tabor PCB?
It measures 210 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logic tabor use?
326 parts, built around the CP2102N-A01-GQFN28R, ESP32-S3-WROOM-1-N8, AMS1117-3.3 and WS2812C. 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 Logic tabor KiCad files?
From the RoboticsBrno/RB3205-Logic repository on GitHub, at the commit this page was made from: the board is hardware/v2.0/Logic_tabor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logic tabor design in my own project?
Its repository states no licence, so its author keeps all rights: ask RoboticsBrno before reusing the design.
