BMI270 is a I2C/SPI based 3D Accelerometer and 3D Gyroscope. We will be using the I2C mode.
Below are the pins connectivity for the BMI270.
As we see, for the BMI270 to operate in I2C mode, CSB pin must be connected to HIGH. SDO pin must be connected to GND for the default I2C address.
Below is the connectivity in the Arduino Nano 33 BLE schematic.
- BMI270 works in the voltage range 1.71V to 3.6V
- Supports I2C Fast Mode Plus meant up to 1MHz speed
- Default I2C address is 0x68 and if SDO is pulled HIGH, address shall be 0x69
Application of BMI270 includes:
- Step counter
- Tap detection
- Wrist gesture detection
- Activity recognition/Motion detection
- Tilt detection
