IMU stands for  Inertial Measurement Unit and is a combination of multiple sensors giving information about the motion of a body. They are used in aircrafts, drones, and other mobile objects to provided accurate data about orientation. Their vast use in projects made us write a list of 10 best IMU modules available in the market. So check out this list and let us know your favourite IMU modules in the comments section below.

10. SparkFun 6 Degrees of Freedom Breakout – LSM6DS3(20$)

SparkFun 6 Degrees of Freedom Breakout - LSM6DS3

This a 6 degree of freedom IMU with an accelerometer and a gyroscope. The full-scale range for the accelerometer is 16g with a combined power consumption of 0.9mA. A positive point for the device is the digital SPI/I2C interface that exhibits far less noise as compared to analog one.

9. Kootek GY-521(2.43$)

Kootek GY-521

This a rudimentary 6DOF IMU with an accelerometer and a gyroscope.  It works on 5v supply and has a 16Bit AD converter.

8. SparkFun IMU Fusion Board – ADXL345 & IMU3000(40$)

SparkFun IMU Fusion Board - ADXL345 & IMU3000

This IMU modules has an impressive 3-axis MEMS digital gyroscope with programmable ranges from +-250 to +-2000 degrees/sec. The interface for accelerometer and Gyroscope is I2C thus reducing noise in the output.

7. SparkFun 6 Degrees of Freedom IMU Digital Combo Board – ITG3200/ADXL345(40$)

SparkFun 6 Degrees of Freedom IMU Digital Combo Board - ITG3200/ADXL345

The IMU board contains ADXL345 accelerometer and MEMS ITG-3200 gyro.  Both sensors can be interfaced using I2C protocol.

6. Sunkee 10DOF 9-axis  L3G4200D (18$)

Sunkee 10DOF 9-axis  L3G4200D

This IMU is ready made for an Arduino. The nine-axis are three-axis gyro + three-axis acceleration + tri-axial magnetic field, while the final DOF is added by the pressure sensor. Though this IMU seems to be a good deal but the accelerometer does not have filters, only the Gyro has two low passes and one high pass filters.

5. Adafruit 9-DOF IMU Breakout – L3GD20H + LSM303(20$)

Adafruit 9-DOF IMU Breakout - L3GD20H + LSM303

Three axes of accelerometer data, three axes gyroscopic, and three axes magnetic (compass) combine to the give the best data. The sensor is also equipped with a 3V regulator with reverse polarity protection which means that you do not need to worry about frying your circuitry mistakenly.
