7.5-inch (800x480) e-paper display DESPI-CO2 adapter board FireBeetle 2 ESP32-E microcontroller BME280 pressure, temperature, and humidity sensor 3.7V LiPo battery with 2-pin JST connector ...

It’s all thanks to its low-power design, enabled by its e-paper display. The build is based around an ESP32 microcontroller, combined with a BMP180 sensor for measuring barometric pressure, and ...

🔄 Data Flow Arduino reads sensor data from BME680 (I2C address 0x76). It sends 8 bytes (2 bytes each for Temp, Pressure, Humidity, Gas) via CAN bus. ESP32-S3 receives the CAN frame, parses it, and: ...
