About the BME688 Gas Sensor Developer Kit

This is the only pre-programmed and ready-to-go Developer Kit for the BME688 in the market. An easy start for the BME688 - we even ship the battery for the realtime clock. 

The developer kit (Basic kit) contains:

  • BME688 shuttle board with the following features:
    • 8 BME688 sensors,
    • 2 buttons for data labelling,
    • Real time clock battery holder
    • SD card slot
  • Adafruit Huzzah32 - ESP32, with pre-soldered headers (Adafruit #3591)
    • with pre-flashed Bosch firmware for the BME688 shuttle board!
  • 16 GB microSD card with config files
  • CR1225 coin cell battery

 The developer kit (Stacking headers) contains:

  • BME688 shuttle board with the following features:
    • 8 BME688 sensors,
    • 2 buttons for data labelling,
    • Real time clock battery holder
    • SD card slot
  • Adafruit Huzzah32 - ESP32, with pre-soldered stacking headers (Adafruit #3619)
    • with pre-flashed Bosch firmware for the BME688 shuttle board!
  • 16 GB microSD card with config files
  • CR1225 coin cell battery

The stacking headers allow you to easily access further I/O from the HUZZAH32, as required for your project. 

The BME688 Shuttle board only contains:

  • only the BME688 shuttle board (no surprises there :-))

Useful for customers who already have the Adafruit Huzzah32, or would like to use the Shuttle Board with their own designs. 

About the BME688 Gas Sensor

The BME688 Gas Sensor by Bosch Sensortec is introduced together with the BME AI-Studio, a software tool to explore data & create machine learning algorithms for your BME688 sensor. 

The BME688 is the first evironmental sensor to support AI algorithms. It digitizes temperature, pressure, humidity,  and gas data. By using machine learning algorithms the BME688 can recognize the footprint of different gas mixtures.

For example, you can teach the sensor to distinguish various types of coffee: Measure the smell of different coffee beans! 

BME AI-Studio will allow you to easily record and label the data. Then use the data to create an individual algorithm, custom-tailored just for your use case!

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, and will support you with documentation and the friendly user interface.

FAQ for the BME688 Gas Sensor Developer Kit

Where do you ship?

We ship world-wide. Please note that we will require upfront payment for shipping outside of Germany if you require manual order processing (including offers). You can also pay using your credit card, PayPal, or any other payment method we offer on this shop.

Can I get an offer for the Developer Kit / get net X terms?

Yes, you can get an offer - please contact us and request an offer. Be sure to provide your full company data.  Within Germany, we are able to offer 14 days net to companies, and 30 days net to government agencies (schools, universities, etc.). 

Outside of Germany, at the moment we offer only upfront payment - or the payment methods in this shop.

Please note that we do have a 10 € net shipping fee within Germany for orders which are processed manually, not through the shop. 

Do you do discounts?

We can offer discounts for projects with volume requirements of the developer kit. Contact us for a quote if you need 25+ BME688 Gas Sensor developer kits.
