ICM42688 Six-axis IMU Module ICM-42688 Attitude Sensor Gyroscope Module Low Drift Intelligent Vehicle Gyroscope

ICM42688-P six-axis attitude sensor module, with excellent performance. The official manual indicates that its performance is superior to bMI270, far exceeding bmi160, mpu6050, icm20602 and other products. It has low temperature drift and low zero offset, and supports IC and SPI driving. This product's VCC supports 5V and 3.3V power supply.

Currently, the product has already been driven by STM32F103's 11C and SPI drivers. It is currently available for order and can provide STM32 drivers, as well as official driver source code. Specific questions can be consulted with the customer service. Using this MEMS sensor for inertial navigation, the official says it can achieve a 5% accuracy (100m error of 5m), and it needs to be combined with the usage scenario and algorithm.

Regarding the option of large zero offset,

generally, only one of the gyroscopes' axes has an initial zero offset exceeding 1 dps, but it will not exceed 2 dps. This is affected by various factors, and theoretically, the algorithm can simply subtract this zero offset, and it is not related to performance. ! It is completely usable and functional.
