Product Description
GY955 is a low cost AHRS module.
Working voltage 3-5v power consumption is small, small size.
Its working principle is through the gyroscope with
Acceleration pass, magnetic field sensor through data fusion
The algorithm finally gets direct angle data.
This module uses the serial (TTL level)
way of communication. The product has high precision and high stability.
Able to get an accurate angle in any position,
Serial baud rate of 9600bps and 115200bps
There are two ways of continuous output and inquiry output,
Can adapt to different working conditions.
With all the microcontroller and computer connection.
