ERICCO INERTIAL TECHNOLOGY ER-MIMU-M02 High Performance MEMS IMU Introduction ER-MIMU-M02 is an inertial measurement unit (IMU) based on micromechanical technology (MEMS), including a built-in MEMS gyroscope with 2°/h (Allan) bias instability and a MEMS accelerometer with 24μg (Allan) bias instability. It is used to measure the three-axis angular rate and three-axis acceleration of the carrier. Through the communication protocol, the gyroscope and accelerometer data with error compensation (including temperature compensation, installation misalignment Angle compensation, nonlinear compensation, etc.) can be solved to obtain the carrier attitude, velocity, displacement and other information. It also has a built-in three-axis magnetic sensor and air pressure sensor. The magnetometer helps with orientation and can be used to calibrate the data and orient it to the correct position. The product has high reliability and strong environmental adaptability. Features Three-axis digital gyroscope: Dynamic measurement range: ±450º/s; Bias instability: 2 º/h (Allan variance); Angular random walk: 0.08º/√h. Three-axis digital accelerometer: Dynamic measurement range: 16g; Bias instability: 24μg (Allan variance); Speed Random Walk: 0.02m/s√h; High reliability: mean time between failures > 20000h; Ensure accuracy over the full temperature range (-40°C~80°C): Built-in high-performance temperature calibration and compensation algorithm; Communication interface: 1 SPI, slave mode. Application Space-based fields: unmanned aerial vehicles, aerial photography, agricultural plant protection, photoelectric detection stability; Land-based fields: vehicle navigation, vehicle satellite communications, forest and land monitoring, high-speed railway track inspection; Sea-based fields: hydrological Measurement, waterway detection, shipboard positioning communication, unmanned surface vehicle.

ERICCO INERTIAL TECHNOLOGY ER-MIMU-M02 is an autonomous sensor system that automatically activates when an active power supply is present. Once the initialization process is complete, it begins sampling, processing, and loading the calibrated sensor data into the output registers, which can be accessed via the SPI port. The SPI port is usually connected to a compatible port of the embedded processor, and the connection diagram is shown in the figure. Four SPI signals support synchronous serial data transmission. In the factory default configuration, the DIO2 pin provides a data-ready signal;...

ERICCO INERTIAL TECHNOLOGY 2.1 SPI read and write timing Read sensor data The ER-MIMU-M02 automatically starts and activates page 0 for data register access. After accessing any other page, the 0x00 should be written to the PAGE_ID register (DIN = 0x8000) to activate page 0 in preparation for subsequent data access. A single register read operation requires two 16-bit SPI cycles. In the first cycle, the bit allocation function in Figure 1 is used to request a read of the contents of a register; In the second cycle, the register contents are output via DOUT. The first digit of the DIN command...
