Product description: Gravity - BMI160 6DoF IMU - 3-axis accelerometer and gyroscope - DFRobot SEN0250
A 6-axisinertial sensor equipped with the Bosch BMI160 MEMS chip. The module integrates a 16-bit 3-axisaccelerometerand a 3-axisgyroscope. It is used to measure linear acceleration in the ranges± 2 g / ± 4 g / ± 8 g / ± 16g and angular velocity in the range± 125 dps / ± 250 dps / ±500dps / ± 1000 dps / ± 2000 dps. It is characterized bylow power consumptionandhighreadingaccuracy. It is used as an additional element for smartphones, tablets and other mobile devices. It can be used to count steps, as a recorder during running and other exercises. It has a built-in LDO power management circuit, works with a voltage rangefrom 3.2 V to 6 V. It usesI2Cbus to communicate with the controller module.

Pinout and connection diagram
The sensor module can be connected to the controller in two ways: using theGravityconnector or solder fields. The kit includesmounting and connection componentsfor each option. Connect the components according to the following relationships:
- VCC ("+") - supply power to the circuit in the range from 3.2 V to 6 V
- GND ("-") - system ground
- SCL (C) - I2C interface clock line
- SDA (D) - I2C interface data line
- INT1 - configurable interrupt 1 output
- INT2 - configurable interrupt 2 output
- SDO - I2C interface address selection
- GND - 0x68
- VCC - 0x69 (default)
