How do I connect the ICM-20948 to an ESP32 PICO D4?

s_f1
s_f1 over 4 years ago

Hello everyone, I am trying to add this ICM-20948 (data sheet- https://product.tdk.com/system/file...l/imu/data_sheet/ds-000189-icm-20948-v1.3.pdf). I am just a beginner at this, not sure wether I have connected it correctly.

 

I am trying to use the I2C connection with this to my esp32 pico d4, but not sure wether I have connected it correctly, hence I have not connected the SDA and SCL to the MCU. I am getting confused with the SDO/ADO, SDA/SDI, SCL/SCLK pins. I have shared my schematic down below. Which do I use for a standard I2C connection?

 

Thanks a lot for your help!

    Hi, The pinout for the ICM-20498 in I2C configuration is shown in Figure 4a on page 20 of the datasheet you linked. SDA and SCL are clearly marked. ADO is used to set the LSB to avoid address conflicts…
