## 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.

Review: Hasta el momento ha trabajado bien, se puede calibrar con la herramienta del fabricante para Windows, así como la obtención de lecturas. Se trabaja muy bien en ROS, hay algunos paquetes desarrollados, sin embargo, para implementarla en los proyectos se deben tener ciertos conocimientos del tema.
Review: This is a great piece of hardware. I also highly recommend getting Witmotion's TTL cable to go with this. Long story short, I tried using the MPU6050 through I2C with some high torque servos to make a dynamic balancing test rig. Rapid movement of the servos caused what I think is back EMF, which is what interfered with the I2C bus, and caused my entire experiment to freeze. After months of disappointment and a broken servo, I decided to give up using I2C and give this module a try. I noticed that Witmotion had sample codes that work with C++ but not for python. So the first thing I did was to write a python code which is now available on Github (I can not post the link directly here, but a simple search on Github can find it). So far, everything works fine. My servo balancing setup, which includes this module and a mini maestro servo controller, does not seem to be freezing anymore even after I violently shake it.

## Questions & Answers

**Q: hello,this device is programmable? Can I choose the baud rate and the data output rate? Where I can found the command protocol datasheet**
A: Hi   When connect the power,the device will be work.and it can not be reprogramable.and you can choose baudrate ,the default is 9600,I give the link for the document and the PC software,you can download it.thanksJY901 User manual: https://drive.google.com/file/d/0B8PmY6nhQadKQm1YNS1jZml4OVE/view?usp=sharingQuick start:https://drive.google.com/file/d/0B8PmY6nhQadKeEdBOV90WmhNRU0/view?usp=sharingJY-901 material:https://drive.google.com/file/d/0B8PmY6nhQadKLWdxN2VNY1E1OWc/view?usp=sharing

**Q: Is it possible to record the data graph for playback later as a moving graph?**
A: Yes it is possible.
Data can be recorded and played back in our software.

**Q: On the magnetic channel is there a way to change it to display from 0 to 359 degrees instead of + or- degrees? (it's for a radio telescope azimuth).**
A: Dear sir or madam,
Thanks for reaching out and let me know your concern. 
Sorry for the delayed response. 
Our company is on Chinese New Year Vacation from 1st Feb. to 1st March. 2020. 
Even on vacation, the email will be replied to within 2 working days. Your understanding and patience would be hugely appreciated. 

1. The degrees can only be +- format. It is a fixed design

**Q: where can I find the app for mobile phone where I can have my data recorded**
A: Hello Kunde, 
Thank you for reaching out and letting me know this situation. 
Link to download the app for Android mobile phone. 
https://drive.google.com/open?id=1d0j8IoDZEwZTNcu8oAM_WHHn5mgs5HvU

Keep me updated if you need any further assist. Always online to serve your queries.

There will be a record button and you can easily record the data according to the config setting. The data will be recorded and output as a txt file.

First, the 4pin connector would not stay in. Second, although it initially kind of worked, it became useless after a couple of recalibrations. I hope to return it.
