C3-Mini

Grab the C3-Mini microcontroller and build your own device, by installing 7 different sensors for getting a Barometer, Hygrometer, Luxmeter, Motion Detector … all for free

What is the C3-Mini?

The ESP32-Mini was the successor of the D1-Mini, comes with added Bluetooth and is now the predecessor of the latest C3-Mini™, which we recommend to stay future proof with respect to the upcoming Matter standard.

For flashing C3-Mini successfully, you need to hold the BOOT-Button, click in parallel the RST-Button for a moment while still keeping BOOT button pressed and then start WebFlashing. Once Flashing started you can release the BOOT-Button. Whenever you want to quick change a sensor, do the same procedure. We know this is tedious, compared to old ESP8266 / ESP32 boards. Therefore we work on convenience measures against it.
