The QMI8658C is a complete 6D MEMS inertial measurement unit (IMU) with 9-axis sensor fusion and specified system level orientation accuracy. When using the QMI8658C in combination with the supplied XKF3 9D-sensor fusion, the system features an accurate ±3° pitch and roll orientation, and a ±5°yaw/heading typical specification.
With tight board-level gyroscope sensitivity of ±3%, gyroscope noise density of 15 mdps/√Hz, and low latency, the QMI8658C is ideal for high performance consumer and for industrial applications.
The QMI8658C incorporates a 3-axis gyroscope and a 3-axis accelerometer. It provides a UI interface (supporting I3C, I2C and 3-wire or 4-wire SPI) .
