Mingjiada Electronics supplies the Bosch BMI088 high-performance Inertial Measurement Unit (IMU) – optimised specifically for drone and robotics applications

BMI088 Product Overview

The Bosch Sensortec BMI088 is a high-performance 6-axis Inertial Measurement Unit (IMU) that integrates an advanced 16-bit digital triaxial gyroscope and a versatile 16-bit digital triaxial accelerometer. This sensor enables high-precision orientation measurement and motion detection along three orthogonal axes, making it an ideal IMU solution for drone and robotics applications.

As a specialist supplier with nearly thirty years’ experience in the distribution of electronic components, Mingjiada Electronics has long supplied genuine Bosch sensor chips. Its product range covers inertial measurement units, barometric sensors, accelerometers and more, providing high-performance hardware support for drone flight control, attitude estimation, navigation and environmental perception. Leveraging a global supply chain network and a stock of over 2 million SKUs, Mingjiada provides customers with a one-stop procurement service ranging from sample procurement to mass production, ensuring genuine, original chips, stable supply and rapid delivery.

BMI088 Key Features

1. Excellent vibration resistance

The BMI088 utilises Bosch’s proven automotive-grade MEMS technology and is specifically designed to effectively suppress high-frequency vibrations above several hundred Hz caused by resonance in PCB or complete system structures. Its outstanding vibration robustness enables it to maintain precise attitude control even during high-speed manoeuvres of drones or in strong wind conditions.

2. Excellent temperature stability

The BMI088’s gyroscope features a bias stability of less than 2°/h and a temperature coefficient of offset (TCO) of less than 15 mdps/K; its extremely low TCO and sensitivity temperature coefficients help to reduce system-level design effort and costs.

3. Wide Measurement Range and High Accuracy

The accelerometer’s measurement range extends up to ±24g, preventing signal clipping under strong signal exposure; the gyroscope’s range reaches up to ±2000°/s, meeting the measurement requirements of highly dynamic motion scenarios. 16-bit digital output ensures high-precision data acquisition.

4. Flexible Integration Design

The gyroscope and accelerometer can operate independently or be linked to enable data synchronisation. On-chip FIFO buffers and an interrupt controller further simplify system integration. Digital interfaces (SPI or I²C) and a wide VDDIO voltage range provide a high degree of flexibility for system design.

5. Compact Package

The compact LGA package measuring 3.0 mm × 4.5 mm × 0.95 mm is suitable for space-constrained drone and robotics applications.

Typical Applications

1. Drone Flight Control and Navigation

The BMI088 serves as the core sensor in drone flight control systems, responsible for real-time measurement of the aircraft’s acceleration and angular velocity to perform attitude calculation. Its high vibration robustness ensures that the drone maintains precise attitude control even during vigorous manoeuvres or in strong winds. Sweet Potato Robotics has deeply integrated it with the Xuri S600 computing platform, utilising the ‘SoC unified master clock’ architecture to synchronise the clocks of all devices—including the IMU, cameras and motors—thereby resolving timing asynchrony and long-term drift issues at their source.

2. Industrial Robots and Motion Control

In industrial robots, autonomous driving platforms and collaborative robots, the BMI088 provides high-precision attitude feedback and motion detection, supporting precise trajectory control and stable operation. NVIDIA Isaac ROS already offers official driver support for the BMI088, enabling high-precision orientation measurement and motion detection in robots.

3. Consumer Robots

Consumer-grade products such as domestic robot vacuum cleaners, social robots and self-balancing scooters also benefit from the BMI088’s high vibration resistance and temperature stability, enabling reliable attitude perception even in complex ground conditions and amidst motor vibration interference.

4. Camera Stabilisation Systems

The BMI088 is also widely used in attitude stabilisation control for drone aerial photography gimbals and handheld stabilisers, providing precise angular velocity feedback to achieve rapid-response stabilisation.
