Questions
How big is the BrailleBox PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BrailleBox use?
3 parts, built around the PCA9685PW. 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 BrailleBox KiCad files?
From the fabkkk/BrailleBox repository on GitHub, at the commit this page was made from: the board is hardware/braillebox/braillebox.kicad_pcb and its schematic hardware/braillebox/Seeed Studio XIAO ESP32/01 Descriptions.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BrailleBox design in my own project?
Its repository states no licence, so its author keeps all rights: ask fabkkk before reusing the design.
