10DOF sensor module combining accelerometer, gyroscope, compass, and barometer for navigation and stabilization projects.
The GY-89 is a 10-degree-of-freedom (10DOF) inertial measurement unit (IMU) module that integrates the LSM303D accelerometer/magnetometer, the L3GD20 3-axis gyroscope, and the BMP180 barometric pressure sensor. This compact board provides comprehensive motion tracking capabilities, measuring linear acceleration, angular rate, magnetic heading, and altitude.
Designed for robotics, drone stabilization, and inertial navigation projects, the module communicates via I2C or SPI interfaces, ensuring easy integration with microcontrollers such as Arduino and Raspberry Pi. The BMP180 delivers high-precision pressure and altitude readings, while the LSM303D and L3GD20 provide accurate motion data fusion.
