Bosch BME688 Development Kit

Added to your shopping cart

Bosch Sensortec’s BME688 Development Kit allows for testing and developing use cases based on temperature, barometric pressure, humidity and gas sensing. The BME688 is the first environmental sensor to support AI algorithms and can detect gases by measuring their unique electronic fingerprint to distinguish different gas compositions. This enables a broad spectrum of new applications.

The BME688 Development Kit can be configured with the BME AI-Studio Software. This allows to optimize performance, ODR and power consumption on specific application needs. Featuring eight BME688 sensors, the board allows you to test and gather data with more than one configuration at the same time. This significantly increases statistics and reduces development time as well.

You don't have to be a data scientist or expert in neural networks to use BME AI-Studio. It is designed with the "normal" user in mind, includes support documentation, and has a user-friendly interface.


  • Users should avoid touching the metal housing of the BME688 sensors.
  • Sold Separately: Users will also need a microSD card (32GB or less), CR1220 coin cell battery, an ESP32 Thing Plus development board, and an Android phone when using the BME AI-Studio.
  • How is the BME688 different from the BME680?
    • The BME680 does not support AI features.
  • Can users test the AI software it with the current BME680?
    • No, this is not possible, as the BME680 does not have the necessary H2S gas scan function.

  • Bosch BME688 Evaluation Board
    • 8x BME688 sensor array
    • 2x buttons for data labeling
    • Real time clock
      • CR1220 coin cell battery holder (Battery not Included)
    • µSD card slot (SD Card not Included)

Bosch BME688 Development Kit Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Well I purchased this board along with the Huzzah32 board and can't get it to record to the SD. I have seen many other people have this issue, and as of yet no solution.

    What has to be on the micro SD card to test (run) an algorithm with the 688?

  • Member #1739876 / about a year ago / 1

    Note to anyone: the board can be used WITHOUT an ESP32 board. As a standalone device it can record data to an SD card, and data can be trained by the BME AI-Studio application (Linux/Mac/Windoz), see the BME AI-Studio doc link above; also since the board has a ¨feather" footprint, many board with that footprint (and with an MCU other than an esp32) will be able to deploy your trained algorithm.
