HW-290/GY-87 10DOF Sensor Fusion Module MPU6050+HMC5883L+BMP180 Chip Sensor Fusion 3-Axis Accelerometer Gyroscope Magnetometer
 
The GY-87 is a 10-degree-of-freedom (10DOF) sensor module that integrates an MPU6050 (3-axis gyroscope + 3-axis accelerometer), HMC5883L (3-axis magnetometer), and BMP180 (barometric pressure/temperature) into one board. It operates on 3-5V, communicates via I2C, and is ideal for drones, robotics, and navigation, providing comprehensive orientation and altitude tracking data.
