Teyleten Robot GY-291 ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module for Arduino IIC/SPI Transmission

The product looks great , quick shipping , I cant wait to try the for a vibration analyst project . Only recieved 3 of the 5 sensors quoted in the ad. Oh well I didn't need more than the three for now .

If you have a 3D printer and want to greatly improve the performance of the print quality, this is for sure your way to get the job done. There are a number of videos and web base help to figure out the wiring and process to interface these ADXL345 accelerometers to your printer to measure the frequencies and what process to include to cancel the vibrations out. By connecting the ADXL to a Raspberry Pi Pico, you can then connect to any other Raspberry Pi by USB connection to use this.All in all a great product that greatly improves 3D print quality using Input Shaping. Well worth a full 5 Stars!

Bought a pack of 5pcs but received only 3..

I bought these to measure resonance levels from vibrations in a 3D printer (a feature in Klipper firmware). Hooked these up to a Raspberry Pi and they worked fine.Basically, the firmware vibrates the parts back and forth at various frequencies and using this accelerometer it can determine which frequencies move the most (resonant frequencies). It can then compensate for this and remove "ringing patterns" caused by resonance.The whole process worked fine using these accelerometers.Great price for these as well.

Product description says 5 pieces and the picture shows 5 boards and 5 pin headers. But I only received 3 boards and 3 pin headers.Misleading advertising.
