BMI270: 6 axis inertial measurement unit


This sample application configures the accelerometer and gyroscope to measure data at 100Hz. The result is written to the console.



This sample uses the BMI270 sensor controlled using the I2C interface. Connect Supply: VDD, VDDIO, GND and Interface: SDA, SCL. The supply voltage can be in the 1.8V to 3.6V range. Depending on the baseboard used, the SDA and SCL lines require Pull-Up resistors.

Building and Running

This project outputs sensor data to the console. It requires a BMI270 sensor. It should work with any platform featuring a I2C peripheral interface. It does not work on QEMU. In this example below the nRF52840 DK board is used.
