WITMOTION 【9-Axis Inclinometer Module】WT901 High-Accuracy Acceleration+Gyroscope+Angle (XY 0.05° Accuracy)+Electronic Compass with Kalman Filtering, MPU9250 200Hz AHRS IMU for PC/Android/Arduino

This sensor works like is says on the tin. Working with the example code was a good way to come up to speed on how to communicate with the device and try out a few of the functions before I went into my own code. The documentation was as would expect with these types of sensors; a bit vague at times but once I figure out what it is calling out it makes sense.I wouldn't necessarily put this into production quantities but the short is it is a fairly inexpensive sensor that let me prototype up a design idea to see if it merited further investigation. For that, or for other hobbiest projects I think this is a great sensor to get your feet wet.

I used UART. The software they recommend is very good and almost a must to easily configure the device, with a USB to UART cable. Amazing accuracy for the price, but very difficult to interface with.Their online code samples are not good at all, but you can make your own or find things on github.For Python I would recommend the pywitmotion library on GitHub. All the heavy lifting has been done and its easy to implement.

I find the reviews of this very confusing. Some say that the promised example code doesn't exist or that they weren't able to interface with the device due to lack of documentation. All of that is just plain wrong. If you actually read the manual it will point you to a github page that has been there since at least 2020. It has example code, instruction manuals, and all the interface information required to get these boards working.I took the example arduino code and copy and pasted it into a new sketch and it immediately worked, zero effort.I like this little board and especially the M0 ARM that you communicate with (instead of directly talking to the sensors).I talk to it via I2C but serial is also a good option if that fits your application better. The example Arudino code shows the registers in I2C to read for each available measurment.

Excellent job on how these guys have made such a complicated device so easy to use. There is a lot going on with the fusion algorithms that go into this and having done this myself with all the code that is involved in getting this to work, these guys have removed a lot of the complexity and provided a fairly easy-to-use interface. Very good documentation (assuming you can find it all) and good videos made it fairly straight forward to get it to work OOB (out-of-the-box) and calibrate it. From what I have seen from using competing devices, this by far is the easiest to use and get working - I highly recommend it! Having an I2C and a UART interface is a huge plus - doesn't take long to get it up and running and providing meaningful results.

This product is very easy to use and has multiple ways to access its function, by PC Apps, Smartphones, and embedded programming. Two communication protocols are available: Serial and I2C. I'm using it for a capstone project so we use the serial portal to connect to the Arduino board. There are numerous tutorials and they even got YouTube video demos!The support staff is quick and helpful. Just email them and they will promptly answer your questions (with more documents provided). Please understand that the company is based in Asia so you should expect some reasonable delay due to time zones.Overall, very good experience developing it.
