Le blog de l'entreprise Mingjiada Supply/Recycle ST LSM6DSL iNEMO 6DoF Inertial Measuremen Unit - UAV Sensor IC

With the rapid development of consumer drones, industrial drones, FPV racing drones, gimbal cameras, robots and smart equipment, high-precision, low-power, compact Inertial Measurement Units (IMUs) have become core components for attitude estimation, flight stabilisation and motion control.

ST (STMicroelectronics)’s LSM6DSL, part of the iNEMO series of 6DoF IMUs, integrates a 3-axis accelerometer and a 3-axis gyroscope. Thanks to its low power consumption, high performance, extensive embedded functionality and compact packaging, it is widely used in drone flight control, gimbal stabilisation, wearable devices, IoT terminals and industrial control applications.

Shenzhen Mingjiada Electronics Co., Ltd. – Long-term supplier and recycler of the [ST] LSM6DSL | iNEMO 6DoF Inertial Measurement Unit (IMU), providing stock availability, BOM fulfilment and inventory recycling services for drone and embedded systems customers.

ST LSM6DSL: iNEMO 6DoF Inertial Measurement Unit (IMU)

The LSM6DSL is ST’s 6-degree-of-freedom inertial measurement unit, utilising a system-in-package design. It integrates a 3-axis accelerometer and a 3-axis gyroscope, supports SPI and I²C digital interfaces, and features a 4 Kbyte FIFO, programmable interrupts and a variety of embedded motion detection functions.

The LSM6DSL supports the requirements of mainstream operating systems, offering real-time, virtual and batch-processing sensor modes, and is equipped with 4 KB of memory for dynamic data batch processing.

The LSM6DSL’s acceleration measurement range is ±2/±4/±8/±16 g, whilst its angular rate range is ±125/±245/±500/±1000/±2000 dps.

The LSM6DSL offers excellent resistance to mechanical shocks, making it the preferred choice for system designers developing and manufacturing reliable products.

Embedded temperature sensor

[ST] LSM6DSL – iNEMO 6DoF Inertial Measurement Unit (IMU), designed for smartphones and battery-powered IoT devices, gaming, wearables and consumer electronics.
In unmanned aerial vehicle (UAV) systems, the LSM6DSL serves as one of the core sensors in the flight control IMU, used for:
Attitude estimation: By measuring angular velocity via the gyroscopes and tilt via the accelerometers, combined with Kalman or complementary filtering, it estimates the aircraft’s attitude in real time;
Flight stabilisation: It provides attitude feedback—such as roll and pitch—to the flight controller, assisting with motor speed control to achieve hovering and stable flight;
Gimbal stabilisation: It detects gimbal shake and airframe vibration, driving brushless motors to provide counter-compensation, thereby enhancing image stability;
Navigation assistance: Works in conjunction with magnetometers, GPS, barometers, visual sensors and ToF modules to enable heading estimation, altitude hold, obstacle avoidance and path planning;
Remote control and handheld devices: Used for motion control via remote controls, motion tracking and gesture recognition;
Industrial drones: Motion sensing and vibration monitoring in applications such as inspection, surveying, agricultural crop protection and security surveillance.
