Mingjiada Supply/Recycle ST LSM303 Ultracompact 6-Axis High-Performance E-Compass Module

Shenzhen Mingjiada Electronics Co., Ltd. – Long-term supplier and buyer of ST (STMicroelectronics) LSM303 series 6-axis IMU electronic compass modules. The LSM303 is an ultra-low-power, high-performance System-in-Package (SiP) product that integrates a 3-axis digital linear accelerometer and a 3-axis digital magnetometer within an ultra-compact 2.0mm × 2.0mm × 1.0mm LGA-12L package, forming a complete 6-axis electronic compass solution.

The LSM303 offers user-selectable full-scale linear acceleration ranges of ±2g, ±4g, ±8g and ±16g, and can measure acceleration with output data frequencies ranging from 1 Hz to 6,400 Hz. The device has a magnetic field dynamic range of ±50 gauss, with output data frequencies ranging from 10 Hz to 100 Hz. The LSM303 incorporates an I²C serial bus interface supporting Standard Mode, Fast Mode+ and High-Speed Mode (100 kHz, 400 kHz, 1 MHz and 3.4 MHz), as well as a standard SPI serial interface.

LSM303 Specification Details:

Supply voltage: 1.71 V to 3.6 V

Operating temperature: –40 °C to +85 °C (Industrial grade)

Communication interfaces: I²C (up to 3.4 MHz) / SPI (3-wire/4-wire)

Output accuracy: 16-bit digital ADC output

Accelerometer range: ±2 g / ±4 g / ±8 g / ±16 g (programmable)

Magnetic field dynamic range: ±50 Gauss

Power consumption in high-resolution mode: 250 µA

Power consumption in low-power mode: <60 µA

Standby power consumption: 1.5 µA

Package type: LGA-12L, 2.0 × 2.0 × 1.0 mm

LSM303 Product Features and Advantages

Extremely low power consumption: Power consumption is less than 60 µA in combined low-power modes, with standby consumption of just 1.5 µA, significantly extending the battery life of battery-powered devices;

Ultra-compact package: 2 × 2 mm LGA package, occupying minimal PCB space, making it ideal for portable devices with limited space;

Excellent value for money: A pure 6-axis compass solution without a gyroscope, costing significantly less than an IMU with a gyroscope;

Flexible power management: The accelerometer and magnetometer can be switched on and off independently, supporting segmented power control;

Hardware interrupt output: Supports hardware interrupts for free-fall, motion detection and magnetic field detection, eliminating the need for the MCU to perform polling;

Embedded FIFO: Integrated 32-level FIFO buffer reduces the need for host processor intervention;

Embedded temperature sensor: Supports temperature compensation to ensure measurement stability across a wide temperature range

LSM303 Typical Application Scenarios

Consumer Electronics and Smart Wearables

Smartwatches/fitness trackers: electronic compass, raise-to-wake, step counting, fall detection, movement posture tracking
