Integrating Bosch Sensortec MEMS Sensors into Custom PCB Design

[ashnichloe67]

Hey guys!🙂

I am building a custom PCB project, and I'm excited to use Bosch Sensortec sensors to add some cool features! Specifically, I'm looking at the BME280 for environmental stuff (temperature, pressure, etc.) and the BMI270 for tracking movement.

Here's where I need some guidance:

1. PCB Design Do's & Don'ts: Any tips on how to design my PCB to get the most accurate readings from these sensors and avoid interference?
2. Software Savvy: Does Bosch Sensortec offer any software libraries or drivers that make it easier to connect these sensors to microcontrollers like STM32 or ESP32?
3. Troubleshooting Toolbox: If I run into problems while integrating these sensors, where can I find help or resources? Are there any common mistakes I should avoid?

I also check this: https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/Reading-the-Chip-ID-of-BMX-160-Sservicenowensor-via-I2C-using-Python/m-p/76017#M14616  Basically, any advice or recommendations you experienced folks can share would be amazing!

Thanks a bunch,

Hi ashnichloe67,

Thank for your inquiry.
You can refer to HSMI design guide for BME280 and BMI270 from the following official website links.

If you encounter problems during the integration of sensors, you can raise questions on the forum or contact your offline distributor.

If necessary, we can also provide you with the example code of BME280 and BMI270 that we run on STM32 for your reference.
