Questions
How big is the Dual debug probe PCB?
It measures 76 × 45 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Dual debug probe use?
113 parts, built around the MCXN947VDFT, DP83826AIRHBR, MEM2052-00-195-00-A and FXL4TD245BQX. 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 Dual debug probe KiCad files?
From the kevswims/dual-trace repository on GitHub, at the commit this page was made from: the board is dual-debug-probe.kicad_pcb and its schematic dual-debug-probe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dual debug probe design in my own project?
Its repository states no licence, so its author keeps all rights: ask kevswims before reusing the design.
