MPU9250 9-Axis Attitude Gyro Accelerometer Sensor Module
MPU9250 9-Axis Attitude Gyro Accelerometer Sensor Module
The MPU9250 is a 9-axis motion tracking module combining a 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer. It provides precise attitude and heading data for applications requiring orientation sensing, such as drones, robotics, and wearable devices. Its integrated Digital Motion Processor (DMP) offloads complex calculations from the host microcontroller.

Compatibility
The MPU9250 works with any microcontroller supporting I2C or SPI, including Arduino Uno, Nano, Mega, ESP32, and Raspberry Pi. Its I2C address defaults to 0x68 (or 0x69 if AD0 is pulled high). The module runs at 3.3V logic but the on-board regulator allows powering from 5V pins; use level shifters if the host uses 5V logic to avoid damage.
Wiring Notes
For I2C connections, wire VCC to 3.3V (or 5V if using regulator), GND to ground, SCL to the controller's I2C clock, and SDA to data. I2C lines require 4.7kΩ pull-up resistors if not present on the module. To change the I2C address, connect AD0 to logic high. In SPI mode, connect NCS, SCL, SDA, and AD0/SDO lines accordingly.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the MPU9250 module works with Arduino Uno using I2C. Connect SCL to A5 and SDA to A4. Use the popular 'MPU9250' library by hideakitai or SparkFun's library for easy interfacing.
Does it come with headers soldered?
No, the module is shipped with unsoldered header pins. Soldering is required to attach it to a breadboard or connect wires.
Can I use the magnetometer indoors for accurate heading?
The magnetometer can provide heading data indoors, but accuracy depends on calibration to account for hard and soft iron distortions. Use magnetometer calibration routines in your code for reliable results.
