Questions
How big is the SoWeSta PCB?
It measures 42.4 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SoWeSta use?
106 parts, built around the ESP32-C3-MINI-1, BH1730FVC-TR, BME280 and SCD40-D-R2. 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 SoWeSta KiCad files?
From the wir-mo/SoWeSta repository on GitHub, at the commit this page was made from: the board is pcb/SoWeSta.kicad_pcb and its schematic pcb/SoWeSta.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SoWeSta design in my own project?
Its repository states no licence, so its author keeps all rights: ask wir-mo before reusing the design.
