Teknik Özellikler
BMI160 is a compact ultra-low-power 6-axis MEMS inertial measurement unit (IMU) developed by Bosch Sensortec, integrating a 16-bit 3-axis accelerometer and a 16-bit 3-axis gyroscope in one tiny package, optimized for battery-powered consumer wearables, mobile terminals and lightweight embedded motion tracking equipment.
BMI160 Chip
👉 It is not high-precision industrial high-stability IMU for navigation grade equipment.
👉 It is a cost-effective always-on consumer-grade six-axis motion sensor with industry-leading low power consumption, perfect for gesture recognition, step counting, VR/AR head tracking and indoor pedestrian dead reckoning.
Core Key Features of BMI160 IMU
Hardware and IoT product designers select BMI160 for ultra-small size, outstanding power efficiency and rich built-in motion detection logic:
- Integrated Dual 16-bit MEMS Sensors
- Triaxial accelerometer: configurable ±2g/±4g/±8g/±16g measuring range
- Triaxial gyroscope: configurable ±125/±250/±500/±1000/±2000 °/s angular velocity range
- Hardware synchronous sampling for accelerometer & gyro data, eliminates fusion time deviation
- Class-Leading Ultra-Low Power Consumption
- Full operation (accel + gyro active): typical 925~950 μA, far lower than peer six-axis chips
- Always-on step counter / significant motion detection: only 5 μA standby current, supports permanent wake-up monitoring
- Multiple configurable low-power sleep / suspend modes to extend battery life for wearable devices
- Compact Miniature Packaging
- 14-pin VFLGA surface mount package, dimension 2.5 × 3.0 × 0.83 mm³, ultra-thin profile for slim device layout
- Small PCB footprint, fits smart watches, wireless earbuds and miniature handheld modules
- Communication & Data Buffer
- Dual digital interfaces: I2C up to 400kHz, SPI up to 10MHz, compatible with all mainstream MCUs
- On-chip 1024-byte FIFO buffer, reduces host MCU polling frequency and power consumption
