Questions
How big is the L0ggi PCB?
It measures 47.8 × 37.3 mm and has 2 copper layers, 1 mm thick.
What parts does the L0ggi use?
40 parts, built around the CP2102N-A01-GQFN28R, ESP-12F, DHT22 and S8050. 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 L0ggi KiCad files?
From the l0ggi/pcb repository on GitHub, at the commit this page was made from: the board is cad/basic_v100_2021-01-03/l0ggi.kicad_pcb and its schematic cad/basic_v100_2021-01-03/l0ggi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the L0ggi design in my own project?
Its repository states no licence, so its author keeps all rights: ask l0ggi before reusing the design.
