7Semi ICM-20948 9DoF IMU Breakout (MPU-9250 Upgrade)

The 7Semi ICM-20948 9DoF IMU Breakout is a high-performance motion sensor module that integrates a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, offering a complete 9 Degrees of Freedom (9DoF) motion tracking solution. Based on the InvenSense ICM-20948 sensor — an upgraded version of the MPU-9250 — this breakout provides higher accuracy, lower power consumption, and improved noise performance. It communicates through an I²C or SPI interface, making it easy to integrate into embedded systems, robotics, drones, and IoT applications that require precise motion sensing and orientation tracking.
