GY-87 IMU module is a very high accuracy module compared to similar models such as MPU9250 and can provide acceleration, change of angle and strength of the magnetic field in three axes x, y and z. This module is actually a combination of 3 sensors. MPU6050, HMC5883L and a barometric temperature and pressure sensor. The barometric temperature and pressure sensor can be either BMP180 or BMP085. The communication protocol is I2C.
