MPU9250 6-Axis Attitude Gyro Accelerator Sensor Module features the MPU-9250, which is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package. One die houses the 3-Axis accelerometer and gyroscope. Hence, the MPU-9250 is a 6-axis Motion Tracking device that combines a 3-axis accelerometer and gyroscope and a Digital Motion Processor (DMP). It is based on I2C Address, Address: 0x68 by default, 0x69 if AD0 is pulled high.
The MPU-9250 also features an embedded temperature sensor. This module includes pull-up resistors on the SDA, SCL, and nCS lines, pull-down resistors on the FSYNC and AD0 lines, and an onboard 3.3V voltage regulator allowing you to power the module from 5V sources such as an Arduino. If you desire to power the module from 3.3V you can bridge the solder jumper next to the voltage regulator to bypass the regulator.

The MPU-9250 has an embedded Digital Motion Processor that can offload computation of motion processing algorithms from the MCU, allowing it to focus on other tasks. It makes use of information from the accelerometer and gyroscope.

The MPU-9250 communicates to a system processor using either a SPI or an I2C serial interface. The MPU9250 always acts as a slave when communicating with the system processor. The LSB of the I2C slave address is set by pin 9 (AD0). It can process it at high speed and make it available to the host MCU.
The MPU-9250 has an embedded Digital Motion Processor that can be used to off-load computation of motion processing algorithms from the MCU, freeing it up to be doing other things. It uses the data from the accelerometer and gyroscope. It can process it at high speed and make it available to the host MCU.
The MPU-9250 is a high-performance accelerometer and gyroscope option for use in applications such as gesture recognition in gaming, self-balancing robots, toys, cell phones, vehicle navigation, fitness monitoring, and similar applications where detection of movement direction and magnitude along with rotation is desired. Both the accelerometer and gyroscope each make use of three 16-bit ADCs with four programmable ranges for high sensitivity.
This specific MPU9250 module is a 6-axis sensor (3-axis accelerometer + 3-axis gyroscope). It does not contain a magnetometer. While the MPU-9250 silicon chip can support a magnetometer in some configurations, this particular Robocraze breakout board does not include one.
A 6-axis IMU measures linear acceleration and rotational velocity (pitch, roll, and yaw rate), but it cannot determine absolute heading (compass direction). A 9-axis IMU adds a 3-axis magnetometer to provide absolute orientation in 3D space. If your project (like a drone compass or advanced robotics) requires true 9-axis sensor fusion, we highly recommend upgrading to the BNO085 9-DOF Orientation IMU Sensor Fusion Nano Breakout Board.
Yes, this module is highly compatible with projects designed for the gy-9250 or mpu6500 module, as they share similar I2C/SPI communication protocols and register maps for the accelerometer and gyroscope functions.

It is ideal for gesture recognition, self-balancing robots, quadcopters, fitness trackers, and any application where detecting movement direction, magnitude, and rotation is required without needing absolute compass heading.
