Questions
How big is the Wattwiser PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Wattwiser use?
49 parts, built around the ESP32-WROOM-32E, BT136-600D,127, IRM-05-5 and LM2596S-3.3. 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 Wattwiser KiCad files?
From the rndfm/wattwiser_pcb repository on GitHub, at the commit this page was made from: the board is pcb/wattwiser.kicad_pcb and its schematic pcb/wattwiser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wattwiser design in my own project?
Its repository states no licence, so its author keeps all rights: ask rndfm before reusing the design.
