Questions
How big is the EHNS - PCB?
It measures 240 × 207 mm and has 6 copper layers, 1.6 mm thick.
What parts does the EHNS - use?
665 parts, built around the STM32L431CCT6, B1212S-1WR3, GS8722-SR and Π122M31. 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 EHNS - KiCad files?
From the HW9711/EHNS_- repository on GitHub, at the commit this page was made from: the board is EH主控板.kicad_pcb and its schematic DRIVE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EHNS - design in my own project?
Its repository states no licence, so its author keeps all rights: ask HW9711 before reusing the design.
