Questions

How big is the HAT v4 BME280 OLED PCB?

It measures 44.6 × 17.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the HAT v4 BME280 OLED use?

14 parts, built around the BME280. 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 HAT v4 BME280 OLED KiCad files?

From the futureshocked/RaspberryPi-FullStack-Upgrade-Project repository on GitHub, at the commit this page was made from: the board is KiCad projects/RPIFSUPG-RPI-HAT_BME280_OLED_HC12/HAT_v4_BME280_OLED.kicad_pcb and its schematic KiCad projects/RPIFSUPG-ESP32-BME280_HC12/ESP32-RpiFS-upgrade.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the HAT v4 BME280 OLED design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
