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

This board has done everything I’d expect. The pins soldered in easily, it worked as expected, and let me tune my 3D printer easily. I’ve only used it a handful of times after hardware changes but it’s worked great each time. For anyone who wants to try Input Shaper on Klipper, this is a perfect board to use.

I used it with Klipper to do Input Shaper tuning on my customized 3D printer. It works just as you would hope and at a great price! Awesome! I bought 2!

It threw errors when I tried to use a hacked together harness with some old stepper cables and duponts, but making a real harness for it allowed it to work properly. Make sure to get a good connection.Worked great for input shaper on Klipper, exactly as the documentation said.

Works with Klipper. Though a little spotty getting to stay connected, it worked. Used with a Raspberry pi Pico to make a resonance tool for 3d printing.

Once wired up to a raspberry, it works as intended. Made resonance compensation easy using Klipper.4 stars because the pin holes are slightly larger than they should be. The included pins and aftermarket Dupont connector pins fit loosely and can easily fall out

If you're looking for an ADXL345 to connect to your Raspberry Pi for use with Klipper Input Shaper, the HiLetgo GY-291 ADXL345 probably is the correct part for you.The HiLetgo GY-291 ADXL345 is a 3.3 volt part with an SPI interface and can be connected directly to the Raspberry Pi or a Pi 2040 and used for Klipper.If you're attempting to connect to a 5volt MCU you are likely looking for a different part but if you're doing that, you're not the common Klipper User and probably already know what you are looking for.

Use one of these to calibrate Input Shaping with Klipper and it works like a charm! Hood quality ADXL.

You may need to disconnect the GND wire to make it work with Klipper. My setup:Raspberry Pi 3B + Ender 3 V2.
