This IMU module is a small board which all the sensors required for 10 degrees of freedom are placed in. This module communicates with the Arduino or microcontrollers via the I2C interface. Using the existing FreeIMU functions and source code, you can easily use this IMU as an AHRS system in flight controls. You can use this module in VTOLs, model airplanes, UAVS, and also industrial and medical devices.
This sensor has 8 pins:
VIN: Module power supply – 5 V GND: Ground 3V3: Module power supply – 3.3 V SLC: I2C Clock / SPI Clock SDA: I2C data / MOSI pin for SPI SAO/SDO: Address adjust pin for I2C / MISO pin for SPI NCS: Chip Select pin only for MPU-9250 sensor CSB: Chip Select pin only for BMP280 sensor
