Wiring

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 :ref:`nrf52840dk_nrf52840` board is used.
