Questions

How big is the Rp hub75-panel PCB?

It measures 85 × 66 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Rp hub75-panel use?

104 parts, built around the ZD25WQ80CTIGT, AMS1117-3.3, TXM12M0004322CBCDO00T and ZX-XH2.54-10PWT. 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 Rp hub75-panel KiCad files?

From the RoboticsBrno/RP-HUB75 repository on GitHub, at the commit this page was made from: the board is hw/rp-hub75-panel.kicad_pcb and its schematic hw/rp-hub75.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Rp hub75-panel design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
