Questions
How big is the Planewatcher PCB?
It measures 86.1 × 54 mm and has 4 copper layers, 1.65 mm thick.
What parts does the Planewatcher use?
180 parts, built around the TQP3M9036, ADL5513ACPZ-R7, LEA-M8T-0 and AD8138ARZ. 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 Planewatcher KiCad files?
From the plane-watch/hardware repository on GitHub, at the commit this page was made from: the board is planewatcher/kicad/planewatcher.kicad_pcb and its schematic adsboost/kicad/adsboost.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Planewatcher design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
