What are the requirements for an IMU suitable for drones?

As the core component of UAV motion perception during flight, the inertial measurement unit (IMU) fully grasps the motion state of the UAV by integrating data from multiple sensors such as gyroscopes, accelerometers, and sometimes magnetometers and barometers. This information is crucial for flight control, attitude stability and navigation.

Therefore, it is very important to choose an IMU suitable for UAVs, as its performance directly affects the flight control and attitude stability of UAVs.

The ER-MIMU-M02 MEMS IMU integrates gyroscopes, accelerometers, magnetometers and barometers (altimeters), and can provide complete data for UAVs to calculate attitude, speed and position. It has excellent performance and low cost, and can be produced in short cycles, large batches and on a large scale. It is an IMU that is very suitable for UAVs.

**High-precision inertial sensor**

Gyroscope: provides a measurement range of ±450º/s, bias instability as low as 2º/h, and angle random walk of only 0.08º/√h.

Accelerometer: has a dynamic range of ±16g, bias instability of 24μg, and velocity random walk as low as 0.02m/s/√h.

In a wide temperature range of -40°C to 80°C, the built-in high-performance temperature calibration and compensation algorithm can maintain stable performance.

Flight attitude control: Three-axis angular rate and acceleration are the core inputs of flight control algorithms (such as PID control). Through calculation, the attitude, speed, displacement and other information of the drone can be obtained to achieve stable hovering, agile maneuvering and wind resistance of the aircraft.

**Multi-sensor fusion enhancement**

Three-axis magnetometer: ±2.5 Gauss measurement range, assists orientation calibration, and provides magnetic north direction.

Barometer: measurement range 450-1100 mbar, resolution 0.1 mbar, mainly used to provide altitude information, is a key sensor for achieving accurate altitude hold (fixed altitude flight) and vertical position estimation.

**Ultra-thin design**

Using the latest MEMS gyro technology, the volume is compressed to the extreme, with an ultra-thin design of only 14mm thickness and a weight of 50g, which greatly saves drone space and payload.

Through the 1.5W low power design and SPI communication interface, the performance and embedded system adaptability are balanced.
