GY-9250 9-Axis Motion Tracking Sensor Module (I2C/SPI, with Magnetometer) – Original Chip

Description

Product Overview

The GY-9250 9-Axis Motion Tracking Sensor Module is a high-performance inertial measurement unit (IMU) based on the original InvenSense MPU-9250 chip. This compact module combines a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer in a single package, providing complete 9-degree-of-freedom (9-DOF) motion tracking for your embedded projects .

The MPU-9250 is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package: one die houses the 3-axis gyroscope and 3-axis accelerometer, while the other houses the AK8963 3-axis magnetometer . This integration, combined with an onboard Digital Motion Processor (DMP), allows the MPU-9250 to perform complex 9-axis MotionFusion algorithms directly on the chip, reducing the processing load on your main microcontroller .

Communication with the module is flexible, supporting both I2C and SPI interfaces. The module includes an onboard 3.3V voltage regulator and pull-up resistors, making it directly compatible with both 3.3V and 5V systems like Arduino, ESP32, ESP8266, Raspberry Pi, and STM32 .

Whether you are building a drone flight controller, a self-balancing robot, a VR headset, an AHRS system, or any application requiring precise orientation tracking, this original GY-9250 module delivers the accuracy and reliability you need.
