Questions

How big is the D1 mini 32 grove PCB?

It measures 31.6 × 37 mm and has 2 copper layers, 1.6 mm thick.

What parts does the D1 mini 32 grove use?

10 parts. 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 D1 mini 32 grove KiCad files?

From the Robotto/D1-mini-grove-shield repository on GitHub, at the commit this page was made from: the board is 32/D1_mini_32_grove.kicad_pcb and its schematic 32/D1_mini_32_grove.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the D1 mini 32 grove design in my own project?

Its repository states no licence, so its author keeps all rights: ask Robotto before reusing the design.
