1. Product Parameters Core Chip: Bosch BMI160 IMU (16-bit resolution) Axes: 6-DOF (3-axis gyroscope + 3-axis accelerometer) Input Voltage: 3.3V–5V DC (built-in LDO regulator; external buck converter required for 4.5V–36V input) Gyroscope Range: ±125°/s to ±2000°/s (programmable) Accelerometer Range: ±2g to ±16g (programmable) Communication: I²C (address 0x68/0x69) & SPI (up to 10 MHz) Current Consumption: 950 μA (full operation), <20 μA (deep sleep) FIFO Buffer: 1024 bytes (prevents data loss) Dimensions: 13mm × 18mm (2.54mm pin spacing) Temperature Range: -40°C to +85°C 2. Key Pin Functions VCC: 3.3V–5V DC input (positive supply; connect regulated power) GND: Power ground Communication Interface: SCL: I²C serial clock SDA: I²C serial data (bidirectional) CS: SPI chip select (active low; pull high for I²C mode) SDO: SPI data output/I²C address select (low=0x68, high=0x69) Control & Interrupt: INT1/INT2: Programmable interrupts (e.g., motion detection, data ready) 3. Common Issues & Solutions Q1: I²C/SPI communication failure? Verify VCC=3.3V–5V; check pull-up resistors (4.7kΩ on SCL/SDA); ensure SDOpin sets correct address (0x68 default) . Q2: Inaccurate gyroscope/accelerometer data? Calibrate via register settings (e.g., zero-g offset tuning); avoid electromagnetic interference; ensure stable power supply (ripple <50mV) . Q3: Interrupt (INT) pin not triggering? Configure interrupt registers (e.g., enable "data ready" in REG_INT_EN1); check physical connection to host MCU .
