Questions

How big is the StratoSTEAM PCB?

It measures 250 × 150 mm and has 2 copper layers, 1.6 mm thick.

What parts does the StratoSTEAM use?

112 parts, built around the ESP32-S3-WROOM-1-N8, TPS54560BDDA, MS5611-01BA03 and TPS54336ADDA. 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 StratoSTEAM KiCad files?

From the robotgtfxry/StratoSTEAM repository on GitHub, at the commit this page was made from: the board is stratosteam/stratosteam.kicad_pcb and its schematic stratosteam/czujniki.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the StratoSTEAM design in my own project?

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