4Pcs GY-291 ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module IIC/SPI Transmission for Arduino (4)

Initially I had trouble getting this connected to my 3d printer. After much frustration, I realized that I had misread the instructions online re how to connect to raspberry pi. It turns out I had flipped it 180 degrees in my head. Totally my mistake. It worked after wiring it correctly.One of the benefits of this is having multiple parts to use helps when you are not great at soldering. This gives you multiple attempts to get it right at a reasonable cost per unit.

They work for what I wanted, I am though missing a set of pins to one of them.TIP:If being used to do input shaper tuning on a 3D printer Klipper software, and you are unable to connect properly/error. You got emf noise between wires. Ribbon wires dont prevent this, but seperating the wires from the ribbon will remove the emf noise enough to connect and run test.

All worked great and produced great graph data powered/read from an Arduino mega. I’ve yet to put them in service on my printer, but based off the test, look promising.

They work as intended. I used them for klipper input shaper.

well you get a 50 50 chance of 1 working . first 2 i soldered up worked great next 2 where dead i guess just know what your getting in to so now i need to order more and puts me out a few days .so time and money .

Used these to do input shaper tuning on a 3D printer running the Klipper software. It is well documented on the Klipper site and these ADXL345 boards worked very easily to accomplish the task.Soldering the headers was easy and the pins are well-labeled so you can follow the cookbook directions in Klipper to get better print quality from your 3D printer.Two thumbs up!

I used these for setting up resonance compensation in Klipper for my Voron and other klipper printer. They did the trick!
