Overview
YIS320 is a high-precision attitude sensor that can measure
the three-dimensional attitude angle (including static and
dynamic inclination), acceleration, angular velocity, and
magnetic field strength information of the carrier.
YIS320 integrates an industrial grade, highly reliable three-
axis MEMS gyroscope, three-axis MEMS accelerometer, and
three-axis magnetic sensor through the embedded YFusion®
high-performance attitude fusion algorithm, high-precision
sensor error compensation algorithm, and strict factory
testing calibration can achieve measurement accuracy of
0.05° roll and pitch angle, as well as measurement accuracy
of 0.2° no reference heading angle and 1° magnetic reference
heading angle.
YIS320 adopts a small-sized design of 22.4 × 22.4 × 9mm,
supports UART and USB interface communication, and
provides corresponding SDKs to facilitate user integration of
applications and shorten development period.
