The SRX-INS00-DEV is a high-performance IMU (Inertial Measurement Unit) that can be used as a base for an AHRS (Attitude Heading Reference System).

Paired with the included C++ library, it enables drift-free attitude measurements over 360° and precise measurements of altitude and vertical speed.

It includes: 

3-axis accelerometer: ICM42688p

3-axis gyroscope: ICM42688p

3-axis magnetometer: MMC5983MA

Barometer: LPS22HB

The compact form of the board makes it ideal for integration into robotic applications such as drones, rovers, inclinometers, compensated tilt compasses...

Next-generation IMU with superior performance

The board includes the best high-performance consumer-grade IMU in terms of noise, temporal and thermal drift, resolution, sensitivity... It is therefore a significantly more performing alternative to the older MPU6050, MPU6500, MPU9250, ADXL335, ADXL345...

One of the best consumer grade barometer!

The board includes one of the best consumer-grade sensor in terms of noise, resolution, sensitivity... It is therefore a significantly more performing alternative to the older bmp085, bmp180 and bmp280...

One of the best consumer grade magnetometer!

The board includes one of the best consumer-grade sensor in terms of noise, resolution, sensitivity... It is therefore a significantly more performing alternative to QMC5883L, HMC5883L, LIS3MDL, perfect for a precise e-compass application

High-performance embedded sensors fusion
