Features

  • The ADXL345 is a small, thin, ultra-low power 3-axis accelerometer with high resolution (13 bits) and measurement range of 16g.
  • The digital output data is in 16-bit twos complement format and is accessible via SPI (3-wire or 4-wire) or I2C digital interface.
  • Its high resolution (3.9 mg / LSB) enables measurement of tilt angle changes of less than 1.0
  • Low-power mode supports motion-based intelligent power management for threshold sensing and motion acceleration measurement with very low power consumption.
  • The ADXL345 is perfect for mobile device applications. It measures static gravitational acceleration in tilt detection applications as well as dynamic acceleration due to motion or impact.

Description

Features: The device offers a variety of special detection features. Active and Inactive Detection Detects the presence or absence of motion by comparing the acceleration on any axis with a user-set threshold. Percussion detection function can detect any direction of single vibration and double vibration action. Free fall detection function can detect whether the device is falling. These functions can be independently mapped to one of two interrupt output pins. The patented integrated memory management system uses a 32-level first- in-first-out (FIFO) buffer to store data, minimizing host processor load and reducing overall system power consumption. Specification:Main chip: ADXL345. Model: GY-291 Power supply :3-5v. Means of communication: the iic / spi communication protocol.

  • 1 out of 2 I ordered worked
As the title said. Ordered two, one worked correctly. The second one would read but the noise level was extremely high. Still ran my input shaper acceleration tests with it, but then tried the other one and noticed immediately that the noise was significantly better (<100 on all axiis whereas it was well over 1000 on some other axiis with the bad accelerometer). Not too upset, stuff happens and sometimes new products don't work. ... show more

  • After some learning was able to get it to work.
This was my first time working with electronics so I I'm not 100% sure on ease of use as I was not 100% sure what I was doing. The end result was lighting up a 3d printed sword and was able to accomplish that with this product.

  • Miscut board
Mis-cut board as you can see in the photo. Still work fine, but close call. Pin header that came with it was also one pin short of a full complement.

  • High failure rate
Bought 2 of these. One worked, the other didn't. No response when queried from Klipper console. Wiring was correct. Got a replacement, that didn't work either. No response again when queried. Fairly high failure rate. When they work, they're great. If you want to give it a shot and don't mind extra soldering work, give it a shot, but order more than what you need. ... show more

  • Don’t be a dummy like me…
It’s a great little resonance tester for the price. Just remember you have to have the ability to solder the header on yourself! As long as you pay attention, and aren’t an idiot— like me— you’ll do just fine. I soldered the pin header on upside down the first time. Don’t. Do. That.

  • Robust and well made.
Used this for input shaper and it works as advertised.

  • Worked great!
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!

  • Worked with a good harness
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.
