The BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. This breakout board includes two JST SM04B-SRSS connectors compatible with the Sparkfun's Qwiic system. Please note this board needs a regulated 3.3V source and no level shifting circuitry is provided. Do NOT connect 5V power or logic. The sensor communicates over the I2C bus, the default address is 0x77. Soldering the jumper on the back of the board, you'll set the optional address 0x76. We wrote a Python 3 library and some examples to quickly start with a Raspberry Pi. Our library includes functions to measure temperature, humidity, pressure and the internal gas resistance of the sensor. In order to calculate the Indoor Air Quality level you'll need additional calculations that at the moment are not performed in our library. Bosch Sensortec has developed a library to provide higher-level signal processing, the Bosch Sensortec Environmental Cluster (BSEC) Software. Check out Schematics and datasheet for more technical specs. Pinouts: 3V3: Input power pin, you must supply 3.3V to this pin to power the sensor. GND: Ground pin. SDA: I2C Serial DAta line, compatible only with 3.3V logic. SCL: I2C Serial CLock line, compatible only with 3.3V logic. ADR: I2C address pin, connect to ground to set 0x76 (alternatively solder the jumper on the back of the board). Dimensions: 25.4mm × 17.78mm x 4.5mm (max height) Raspberry Pi and Qwiic cable NOT included.

Good product, but would not use it
Good product, but would not use it. Too much hassle with the Bosch algorithms. Got an MCU680 instead, plug and play, and gives output on the UART line. Nothing needs to be coded.
