Questions
How big is the Traffic display PCB?
It measures 96 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Traffic display use?
45 parts, built around the STP24DP05B, FFB2907A, AP7361C-Y5 and MBT3904DW1. 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 Traffic display KiCad files?
From the Ratfink/traffic_display_pcb repository on GitHub, at the commit this page was made from: the board is traffic_display.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Traffic display design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ratfink before reusing the design.
