README
sensor-hardware/readme.mdHardware
The board uses the ESP32-C3 microcontroller, which provides both WiFi and Bluetooth connectivity, as well as an integrated USB-JTAG adapter.
The system is powered from a USB Type-C port. The TLV62568DBV buck converter is used to supply the system with 3.3V.
As far as sensors are concerned, the SHT40 is used to measure temperature and humidity, and the DPS310 is used to measure the atmospheric pressure.
JLCPCB was used to manufacture and assemble the board. The jlcpcb folder contains the ordering files.

Questions
How big is the Nuernberg Sensor PCB?
It measures 25 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nuernberg Sensor use?
40 parts, built around the ESP32-C3-MINI-1-N4, TLV62568DBV, DPS310 and SRV05-4. 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 Nuernberg Sensor KiCad files?
From the opendata-nuernberg/open-sensor-platform repository on GitHub, at the commit this page was made from: the board is sensor-hardware/Nuernberg-Sensor.kicad_pcb and its schematic sensor-hardware/Nuernberg-Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nuernberg Sensor 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).
