Questions
How big is the Physiowand PCB?
It measures 49.4 × 95.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Physiowand use?
91 parts, built around the CH340C, ESP32-WROOM-32, AL8860WT and MT3608. 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 Physiowand KiCad files?
From the 1tsMS/Physiowand repository on GitHub, at the commit this page was made from: the board is PCB/PhysioWand.kicad_pcb and its schematic PCB/PhysioWand.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Physiowand design in my own project?
Its repository states no licence, so its author keeps all rights: ask 1tsMS before reusing the design.
