With versatile serial output, developer-friendly sample code, and lifetime technical support, it’s engineered for seamless integration and reliable performance in dynamic environments. ## Description Document: https://wiki.wit-motion.com/english (1)HWT31 high precision accelerometer is good solution for angle measuring，acceleration measurement ,It packs a 3-axis accelerometer and in-built SCA3300 temperature compensation chip which enables its high accuracy. (2) Kalman filter combines accelerometer to get high precision angle measurement,it can be used such as four-axis flight control and self-balancing robot, angle measurement and depth measuring and so on. (3)The module can get accurate attitude in a dynamic environment. Attitude measurement precision is 0.05degrees, high stability. (4)Using high-precision accelerometer , read the measurement data by serial port. With advanced digital filtering technology, reduce the measurement noise and improve measurement accuracy. (5)Using stamps holes gold plating, quality assurance, can be embedded in the user's PCB board Technical Indicator Main Feature: 1 Input voltage: 3.3V-5V 2 Consumption current: typical 10mA 3 Volume: 15.24mm X 15.24mm X 4.4mm 4 Measuring : Attitude angle: 2 axis, X&Y Acceleration: 3 Axis 5 Range: Acceleration: ± 16g, Angle: ±90° 6 The data output frequency 10Hz. 7 Data Interface: Serial (TTL level), 8 Baud rate 115200kps / 9600kps. 9 Provide single-chip analytical sample code. Note: There is no Z-axis angle, because there is no gyroscope built-in.
