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.

Thanks to 8 BME688 sensors on the BME688 shuttle board, you will be able to test and gather data with more than one configuration at the same time. This significantly increases statistics and reduces development time! 

The BME688 is a unique sensor which can be deployed and trained in-field, to tailor it to your real application environment and situations, allowing for improved performance as compared to sensors tailored to one specific gas lead compound during manufacturing.

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. 

The BME688 sensor chip only contains:

  • only the BME688 sensor chip 

Note: the chip has an LGA package - therefore most likely purchasing it is only useful if you're planning to develop your own boards and have pick & place machines to be able to place it on your boards for reflow soldering. 

As the BME688 is pin-compatible with the BME680, and has identical packaging dimensions, etc., you can use the BME680 datasheet for designing your BME688 based solution.

If you are looking for experienced hardware-designers to design a solution for you, we will also be happy to work with you on your project. Please get in touch with us.

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.

The BME688 is pin-compatible with the BME680, the final datasheet for the BME688 will be published in the beginning of April 2021.

FAQ for the BME688 Gas Sensor Developer Kit

Does this sensor measure CO2 and natural gas (Methane)?

Natural gas ("Erdgas" in German) and CO2 can not be measured directly with this sensor. 

If you intend to measure the air quality, this sensor might be an even better fit than measuring CO2, since it can measure VOCs (volatile organic compounds), which are an even better indicator of people breathing out & the air going stale in a room. 

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.

What is the difference between the BME680 and the BME688?

  • The BME680 does not have AI features. 
  • Both chips have an identical pinout 
  • BME688 might require newer driver software, and the BSEC 2.0 library, to make use of the AI features

Can we test the AI software it with our current BME680?

No, this is not possible, as the BME680 does not have the necessary gas scan function.

Can I preorder the BME688 dev kit in the UK ?

Yes, we ship world-wide. Note that delivery to the UK might take additional time once the breakout board is available due to Brexit. Also note that we reserve the right to cancel high-risk transactions from our side - we recommend to pay using PayPal instead of credit cards.  

Once I have the kit, can I have the software and wiring instructions to connect to a Raspberry PI?

Note, this BME688 Shuttle Board / dev kit is NOT compatible with a Raspberry Pi. It is based on an Adafruit Feather board, more specifically an ESP32 microcontroller Board. 

If you are looking to use the BME688 with the Raspberry Pi, our BME688 Raspberry Pi breakout board is just what you need

I really need this BME688 sensor urgently, what can I do?

We have a BME688 breakout board with one BME688 sensor on it - it is available immediately from stock (as of 26.03.2021).
