Questions
How big is the Dart hat PCB?
It measures 114 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dart hat use?
128 parts, built around the LM25088MH-2, PCA9685PW, BMI088 and CAT24C32YI-GT3. 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 Dart hat KiCad files?
From the kemfic/dart-hat repository on GitHub, at the commit this page was made from: the board is dart-hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dart hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask kemfic before reusing the design.
