Questions
How big is the Ws uc06 PCB?
It measures 105 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ws uc06 use?
84 parts, built around the R-78E5.0-1.0, AZ1117CH-3.3TRG1, ESP32-C6-MINI-1 and USBLC6-2SC6. 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 Ws uc06 KiCad files?
From the wildsystems/ws-uc06 repository on GitHub, at the commit this page was made from: the board is hardware/ws_uc06.kicad_pcb and its schematic hardware/power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ws uc06 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wildsystems before reusing the design.
