Questions
How big is the GN ESSP32 PCB?
It measures 48.8 × 50.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GN ESSP32 use?
37 parts, built around the LPS25HB and BQ24074RGTR. 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 GN ESSP32 KiCad files?
From the AineeJames/EcoSense-PCB repository on GitHub, at the commit this page was made from: the board is GN-ESSP32.kicad_pcb and its schematic GN-ESSP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GN ESSP32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AineeJames before reusing the design.
