Questions
How big is the SX70z Normal PCB?
It measures 95.9 × 72 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SX70z Normal use?
52 parts, built around the ESP32-PICO-D4, OPT4001DTSR, SPX3819M5-L-3-3 and 1N4148WS. 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 SX70z Normal KiCad files?
From the ZeshuLiu/SX70z repository on GitHub, at the commit this page was made from: the board is Hardware/MainController/SX70z_Normal/SX70z_Normal.kicad_pcb and its schematic Hardware/Body_controller/BodyControllerForSX70z/BodyControllerForSX70z.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SX70z Normal design in my own project?
Its repository states no licence, so its author keeps all rights: ask ZeshuLiu before reusing the design.
