Product Description
Product Description
The DFRobot Gravity: 9DOF IMU Sensor for Motion, Heading & Orientation (I2C / UART, Plug & Play) SEN0694 is an IMU/AHRS sensor module based on the Bosch BMI323 and Bosch BMM350. It combines 3-axis acceleration, 3-axis gyroscope and 3-axis magnetometer functions in one 9DOF platform for motion and heading-related measurements. With Gravity connectivity plus I2C and UART communication, the module is suited to rapid integration in Arduino, ESP32 and Raspberry Pi prototypes.
The BMI323 provides 16-bit acceleration and angular rate data with acceleration ranges from ±2 g to ±16 g and gyroscope ranges from ±125 °/s to ±2000 °/s. In Normal or High Performance mode, the 6-axis motion sensing path can reach output rates up to 6400 Hz. The BMM350 adds magnetic reference data up to ±2000 µT and supports output data rates from 1.5625 Hz to 400 Hz. An onboard MCU exposes both sensors through one integrated DFRobot library, reducing multi-sensor bring-up effort.
