Questions
How big is the View base PCB?
It measures 81.2 × 81.2 mm and has 4 copper layers, 1.2 mm thick.
What parts does the View base use?
259 parts, built around the ESP32-S3-WROOM-1U-N16R8, SN74LV1T34DBV, HX711 and MT6701CT-STD. 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 View base KiCad files?
From the SeedLabs-it/smartknob-hardware repository on GitHub, at the commit this page was made from: the board is electronics/view_base/view_base.kicad_pcb and its schematic electronics/view_base/view_base.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the View base design in my own project?
Its repository states no licence, so its author keeps all rights: ask SeedLabs-it before reusing the design.
