【WT901C-TTL 9-Axis Vibration Inclinometer】High-Performance Acceleration+Gyro+Angle (XY 0.05° Accuracy)+Digital Compass, Triaxial MPU9250 Tilt Sensor【Kalman Filtering】 for Arduino, Raspberry Pi

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.

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.

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.

Excellent product, well documented good code samples

You'll have to find a windows laptop to configure this IMU (no GUI for Ubuntu) and you'll have to rely on 3rd party ROS2 drivers.
