Mingjiada Supply/Recycle SMI230 Combined Inertial Sensor For Non-Safety Relevant Applications

Shenzhen Mingjiada Electronics Co., Ltd. — Long-standing specialist supplier of SMI230 6-axis IMU modular inertial sensors, genuine original LGA-16 package. This is an automotive-grade 6-axis MEMS inertial measurement unit launched by Bosch, integrating a 3-axis accelerometer and a 3-axis gyroscope, and is widely used in vehicle dead reckoning, industrial attitude detection and motion sensing applications for smart devices. Mingjiada supports spot wholesale, sample procurement and batch order fulfilment, whilst also offering high-price buy-back and cash-on-delivery purchases of surplus SMI230 sensors, providing a one-stop solution for electronic component supply, demand and inventory management.

The SMI230 is a high-performance 6-axis Inertial Measurement Unit (IMU) launched by Bosch, integrating a three-axis accelerometer and a three-axis gyroscope within a compact package. This sensor is specifically designed for non-safety-relevant applications, such as in-vehicle navigation and motion tracking.

As a highly stable 6-axis IMU sensor, the SMI230 holds AEC-Q100 Grade 2 automotive certification. It features excellent stability at both high and low temperatures, low noise and minimal bias drift, and is capable of performing precise attitude calculations even in the absence of a GPS signal. It serves as a core sensing component for in-vehicle navigation, vehicle security systems and industrial inspection equipment.

The SMI230 utilises an LGA-16 package (measuring 4.5 × 3 mm) and features the following key specifications:
Sensor type: Accelerometer + gyroscope, 6-axis
Output interfaces: Supports I²C and SPI digital interfaces
Supply voltage: 2.4 V to 3.6 V
Operating current: 5.17 mA
Operating temperature: –40 °C to 105 °C
Data resolution: 16-bit
Accelerometer measurement range: Selectable ±2g, ±4g, ±8g, ±16g
Gyroscope measurement range: Selectable ±125°/s to ±2000°/s
Standby current: 3 μA

Key Advantages of the SMI230
1. Automotive-grade high precision and excellent stability: The SMI230 six-axis IMU sensor utilises specialised MEMS technology. The gyroscope features low noise and low temperature drift, ensuring stable angle and attitude measurement data in both high and low temperature environments. This effectively resolves data deviation issues in automotive equipment under extreme temperature conditions, meeting the requirements for long-term stable operation in vehicles.
2. Low power consumption and configurability, suitable for multi-scenario development: The sensor supports independent activation/deactivation and synchronous sampling of the accelerometer and gyroscope. It features multiple built-in low-power sleep modes to reduce the device’s overall power consumption, making it suitable for portable smart devices, in-vehicle terminals and industrial wireless monitoring equipment.
3. Strong compatibility, reducing development costs: Hardware pins and software interfaces are compatible with the SMI130; project iterations do not require significant modifications to PCB layout or firmware, substantially shortening product development cycles and facilitating upgrades and replacements for both new and existing projects.
4. Miniature packaging, suitable for lightweight devices: The compact LGA-16 surface-mount package occupies minimal PCB space, meeting the assembly requirements of space-constrained in-vehicle terminals, miniature industrial monitoring equipment and smart wearable posture detection devices.

The SMI230 is suitable for applications with high demands for accuracy and reliability, including but not limited to:
High-end navigation and dead reckoning: Providing precise attitude and position information for in-vehicle navigation systems.
In-vehicle information and toll collection systems: Used for vehicle dynamic data recording and status monitoring.
Vehicle dynamic data recording: Capturing changes in vehicle acceleration and angular velocity.
Tilt, motion, vibration or impact detection: Unaffected by the sensor’s mounting orientation, enabling all-round sensing
