## Description

Product document: https://wiki.wit-motion.com/english(1)WT901 Inclinometer TTL version Gyroscope is good solution for angle measuring，acceleration measurement and angular velocity measurement,It packs a 3-axis gyro and a 3-axis accelerometer and 3-axis magnetic. (2) Kalman filter combines the gyro and 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. (4)Using high-precision gyro accelerometer MPU9250, read the measurement data by serial port and IIC port. With advanced digital filtering technology, reduce the measurement noise and improve measurement accuracy. (5)Using small case, quality assurance, can be installed on the customer's board  Main Feature: 1 Input voltage: 3V-6V 2 Consumption current: typical 20mA 3 Volume: 36mm X 51mm X 15mm 4 Measuring : Attitude angle: 3 axis Acceleration: 3 Axis Angular Velocity: 3 Axis Magnetic 5 Range: Acceleration: ± 16g, angular velocity: ± 2000 ° / s. 6 The data output frequency can reach 200Hz 7 Data Interface: Serial port UART(TTL level), I2C . 8 Baud rate (baud rate 2400-921600 kps. deault 9600kps). 9 Provide single-chip analytical sample code. 10 With GPS connectivity. Acceptable in line with NMEA-0183 standard GPS data 11 4 way expansion port for analog input and digital input and output Note:Angle of Z axis will be accurate because of adding magnetic field correction .Requiring the magnetic unaffected.

## Questions & Answers

**Q: Does this work with srs studio + dof reality and the varjo aero headset?**
A: hello
Not for srs studio + dof reality and varjo aero headphones

**Q: where can I find arduino sample code?**
A: Hello sir, 
Thanks for reaching out and letting me know the concern. 
The WT901C RS232 is RS232 interface which will requires a RS232 to TTL module if you wanna connect this sensor with Arduino. 

Its sample code link as below:

**Q: do these have reverse voltage protection?**
A: Hello,
Our sensors have directional voltage protection. As long as the voltage is not the maximum and the reverse connection time is not long, there will be no problem.
