Description

⚠️ The offered board only includes the sensors and no microcontroller, which must be added additionally and connected to the board to benefit from the stated functionalities.

The SRX-IMU00-DEV is a high-performance IMU (Inertial Measurement Unit) whose size has been minimized to facilitate integration into any robotic system.

Paired with the included C++ library, it allows drift-free attitude measurements over 360°.

It includes:

3-axis accelerometer: ICM42688p 3-axis gyroscope: ICM42688p

The extreme compactness of the board makes it ideal for integration into robotic applications such as drones, rovers, inclinometers...

Next-generation sensors with superior performance

The board includes the best high-performance consumer-grade sensor 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...

High-performance software

Customizable software for sensor reading and configuration, sensor fusion, real-time Fast Fourier Transform decomposition, data logging and communication (CAN, protobuf, mavlink) is proposed for supported platform (esp32s3, teensy 4). Reduced functionalities are proposed for most platforms boards with Arduino framework compatibility.

Embedded sensors fusion
