BMP388 PCBs

Hi,

I was looking into the BMP388 sensor and especially in its connection schematics for SPI communication. The SPI connection diagram proposed in the Bosch datasheet shows only two capacitors in addition of the sensor . But schematics from retailers like Adafruit, BlueDot, ... show a voltage regulator, a bidirectionnal logic level inverter and resistors that don't appear in the Bosch BMP388 datasheet.

My question:"is the connection diagram in the Bosch datasheet sufficient for the sensor to work or do we need to connect the voltage regulator, the logic level converter and resistors to the sensor ?"

Thank you in advance for your response,

Best regards,

Hi,

You can design your own BMP388 PCB library according to the datasheet Section 7.1 outline drawing. Please make sure that there are no traces or vias underneath the BMP388 chip in order to minimize the mechanical stress to the BMP388.

Thanks.
