### Sensor Details
### Device Details

The **Modulino LED Matrix** module uses an 8×12 LED matrix controlled via charlieplexing technology. The LEDs do not have native I²C capabilities. Instead, the matrix is driven by the Modulino's onboard microcontroller (STM32C011F4), which handles the complex timing required for charlieplexing and provides I²C communication.

### Device Not Reachable

If your Modulino's power LED isn't on or the sensor isn't responsive:
If your Modulino's power LED isn't on or the device isn't responsive:
- Ensure both the board and the Modulino are connected to your computer
- Verify that the power LEDs on both are lit
- Check that the QWIIC cable is properly clicked into place
