About this item

  • ADXL345 is a small, thin, ultra-low power 3-axis accelerometer with high resolution (13-bit), measurement at up to ± 16g. Digital output data is 16-bit twos complement format, can be accessed via I2C digital interface or SPI (3-wire or 4-wire).
  • 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.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.
  • Appliactions: It can used in Handsets, Medical instrumentation, Gaming and pointing devices, Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection, Portable gaming.
  • ULTRA LOW POWER: as low as 23 μA in measurement mode and 0.1 μA in standby mode at VS = 2.5 V (typical).

MULTIPLE SENSING DETECT:

Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds.

Tap sensing detects single and double taps in any direction. Free fall sensing detects if the device is falling.

Low-power mode supports motion-based intelligent power management for threshold sensing and motion acceleration measurement with very low power consumption.

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 .

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.

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.

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

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

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!
