Questions
How big is the Bx hub75 PCB?
It measures 69.9 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bx hub75 use?
31 parts, built around the SN65HVD77D and 74LVC4245AD. 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 Bx hub75 KiCad files?
From the shinyblink/ledstream repository on GitHub, at the commit this page was made from: the board is hw/bx-hub75/bx-hub75.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bx hub75 design in my own project?
Its repository publishes it under the ISC licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
