Questions
How big is the Stm32 LORA TEMP PWM PCB?
It measures 55.3 × 35.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32 LORA TEMP PWM use?
88 parts, built around the RFM95W-868S2, BLM21PG221SH1, IRLML0030 and C13. 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 Stm32 LORA TEMP PWM KiCad files?
From the Heorenmaru/Hardware repository on GitHub, at the commit this page was made from: the board is Stm32_LORA_TEMP_PWM/Stm32_LORA_TEMP_PWM.kicad_pcb and its schematic Geiger/geiger/geiger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32 LORA TEMP PWM design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
