Questions
How big is the ESP32-C3 Sensor PCB?
It measures 33 × 54.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-C3 Sensor use?
96 parts, built around the ESP32-C3-WROOM-02-H4, BMP388, RT6150AGQW and DW01A. 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 ESP32-C3 Sensor KiCad files?
From the pellematrose/ESP32-C3_Sensor repository on GitHub, at the commit this page was made from: the board is Hardware/ESP32-C3_Sensor/source_2026-02-19/ESP32-C3_Sensor.kicad_pcb and its schematic Hardware/ESP32-C3_Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-C3 Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask pellematrose before reusing the design.
