Customer Support directed me to repost my enquiry in this forum.

I am developing MIC, a room instrumentation/CCTV prototype intended to be made freely available. We are assessing the BME690 and BMV080 together because their integration into a shared Raspberry Pi 5 architecture needs to be considered early.

The proposed arrangement includes:

• A static BME690 array using twenty BME690 8× Shuttle Boards 3.0, providing 160 sensors: 80 facing upward and 80 facing downward.

• A BMV080 Shuttle Board 3.1 on the moving pan/tilt assembly.

• A Raspberry Pi 5 as the intended shared host.

These are separate shuttle-board products; the revision numbers above are intentional.

BME690 array and training

The shuttle boards would be mounted on both faces of a custom PCB, with airflow above and below. Control electronics may use a separate PCB.

Individual sensors would be assigned to gas or odour recognition tasks, with selections distributed across shuttle boards and upward/downward positions. We do not intend to dedicate every sensor on a shuttle board to the same task.

Apartment background-air recordings and controlled laboratory exposures would support training and independent validation. The laboratory would choose which candidates it can support. Gas density would inform initial position selection, followed by practical testing.

Could you advise:

1. What interface, sensor-selection, power and software architecture would you recommend for acquiring data from 160 BME690 sensors through a Raspberry Pi 5?

2. Can individual sensors within each 8× Shuttle Board use different heater profiles and trained configurations? What practical limitations apply?

3. What validation is recommended when transferring a trained profile between sensors, shuttle boards or replacement sensors?

4. Can data recorded through our custom host system be imported into BME AI-Studio? What recording formats and configuration information must be retained?

5. Are there particular mounting, contamination or thermal considerations for this double-sided arrangement?

BMV080 integration

The BMV080 would operate on a moving assembly, with measurements evaluated after movement has stopped and the assembly has settled.

Could you advise:

6. Which published integration requirements apply specifically to using the Shuttle Board 3.1 in a prototype, particularly optical clearances, cooling, mounting and cable routing?

7. Are there additional recommendations for operation on a pan/tilt assembly, including vibration, settling and measurement timing?

Shared host and Application Boards

We are not proposing to add an Application Board unless it provides a demonstrable advantage over the intended architecture.

8. Can both products operate through the same Raspberry Pi 5 host? Which supported drivers, SDKs and interface arrangements would you recommend?

9. What capabilities would an Application Board provide that are necessary or materially beneficial for this project, particularly during BME690 training and BMV080 evaluation?

10. If an Application Board is recommended, can one board be reused between the two products? Please distinguish sequential use from simultaneous operation and identify the required board revision and software.

We recognise that sensitivity to a gas does not by itself establish reliable identification or concentration measurement. The Bosch-based functions are intended for experimental environmental monitoring, within the published operating limits, without reliance on them for safety-critical protection.

We would welcome answers to the individual questions, references to relevant documentation, and identification of any aspects requiring our own prototype verification. Relevant specification extracts can be provided if useful.

Thank you for your assistance.

Huge thanks

Where can I find documentation for hardware/mechanical integration of the bmp585?

please could you provide mechanical STEP model of sensor BMP581?

Thanks

Andrea

Can you provide us with the official BMA456 driver implementation for the Linux kernel ?

Thank you in advance for your help.

Best regards.

During the sensor evaluation, we identified that the Bosch BNO055 has been classified as NRND (Not Recommended for New Designs).

While the device remains available for existing products, Bosch does not recommend it for new designs due to lifecycle considerations and potential future supply risks.

To mitigate long-term obsolescence and supply concerns, we kindly request you to suggest active 9-axis IMU alternatives that offer similar functionality and are suitable for new product development.

Once the alternative parts are shortlisted, we can proceed with a detailed evaluation covering technical performance, cost, availability, and overall design impact.

We look forward to your recommendations.

Thanks & Regards,

Sathya. D
