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

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!

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.

Was using these to cal vibration on a 3d printer. First one I couldn't get to work, even after messing with the software a lot. So decided just to swap it with another. Luckily the pack came with 3 and the 2nd one I tried work. Haven't tried the 3rd so I'll just assume that one will work as well. For the price it isn't a bad deal. Would be great if all 3 worked out of the box.

Worked easily and as expected for Klipper auto resonance tuning. 3 printers done for cheap when compared to cost of 1 board from Adafruit costing around 20$ each or Sparkfun

I use these for input shaper tuning with Klipper on my Ender 3 V2. They work great, no complaints.

It’s hot and miss with these. Out of the initial 3, only one worked. I needed 2. The replacement pack sent to me had 2 that were good so out of the 6, only 3 worked. Out of the 3 that did work, 1 is reporting values way different than the other 2. I’m not sure if these values mean anything yet but once I get my 3D printer back up and running, I will test them with the input shaper. The other 2 I did test with input shaper led to the same results. If your needing more than one or two, I suggest ordering at least 2 packs. Out of 6 you ought to be able to get a few working and just return the duds

Got these for my Ender 6 to calibrate Klipper. I only needed one, but I guess I have spares now.

Terrible. only came with 3 and i spilled sauce on the package and didnt want to be a jerk and return it, even though it was legit only 3, and i assume they are bad boards seeing the other reviews, but will update if they DO work.

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 .

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

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.

Ad says 5pcs only 3 pcs shipped
