The ICM-42688-P is TDK InvenSense's flagship 6-axis IMU for precision drone and stabilization applications. It offers the lowest noise density available in consumer-grade IMUs — 2.8 mdps/√Hz gyro noise — and supports up to 32kHz output data rate on both gyroscope and accelerometer axes via a high-speed SPI interface at up to 24MHz.
The ICM-42688-P features an additional OIS (Optical Image Stabilization) interface for direct connection to gimbal actuators or image stabilization systems. It's used in the latest Betaflight H7 targets and professional autopilot hardware requiring maximum sensor fidelity.
Key Advantages vs ICM-20602
- Better noise: 2.8 vs 4 mdps/√Hz — cleaner gyro data
- Faster SPI: 24MHz vs 10MHz — lower MCU load
- OIS interface for camera stabilization
- More gyro FSR options including ±15.625 dps for precision
- FIFO up to 8192 bytes for burst reading
