Questions
How big is the Trex uhat PCB?
It measures 89.5 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trex uhat use?
25 parts, built around the WS2812B. 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 Trex uhat KiCad files?
From the urish/real-trex-runner repository on GitHub, at the commit this page was made from: the board is pcb/raspi-hat/trex-uhat.kicad_pcb and its schematic pcb/pi-pico-adapter/pi-pico-adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trex uhat design in my own project?
Its repository states no licence, so its author keeps all rights: ask urish before reusing the design.
