GY-25 is a low-cost tilt angle module. It has an operating voltage of 3-5 V, low power consumption and small size. GY-25 working principle is that it obtains direct angle data through data fusion algorithms based on gyroscopes and acceleration sensors. The GY-25 tilt module communicates with the host computer in a full-duplex manner with TTL level via serial port. This product features high precision and high stability. It can obtain accurate angles at any position, with output baud rates of 9600bps and 115200bps, and two output modes (continuous output and inquiry output).  The GY-25 tilt module can adapt to different working environments. It can be connected to all single-chip microcomputers and computers.
