Questions
How big is the Phase interferometer PCB?
It measures 54.3 × 76.1 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Phase interferometer use?
78 parts, built around the RP2040, ADE-1+, BGA2803 and W25Q128JVSIQ. 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 Phase interferometer KiCad files?
From the mpkendall/phase-interferometer repository on GitHub, at the commit this page was made from: the board is PCB+Schematic/phase-interferometer.kicad_pcb and its schematic PCB+Schematic/phase-interferometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phase interferometer design in my own project?
Its repository states no licence, so its author keeps all rights: ask mpkendall before reusing the design.
