Questions
How big is the Alidade PCB?
It measures 277.2 × 107.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alidade use?
212 parts, built around the NRF54L15-QFAA-R, FT200XD-R, BAT54 and 19-237/R6GHBHC-A01/2T. 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 Alidade KiCad files?
From the KeatonClark/alidade repository on GitHub, at the commit this page was made from: the board is hw/alidade.kicad_pcb and its schematic hw/alidade.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alidade design in my own project?
Its repository states no licence, so its author keeps all rights: ask KeatonClark before reusing the design.
