I was able to use it with klipper to do the Resonances test for the 3 axis.

This works fine for Klipper resonance compensation (input shaping). Using it with a RP2040 board as I have multiple Klipper printers.

These seem to be working fine so far, but be aware that the circuit boards look like they were snapped from a larger sheet rather than cut. This leaves a very coarse and abrasive appearance on the perimeter of the board, which will collect dust and fibers if left exposed.

I've been constantly modifying my 3D printer the past few weeks so I need to make measurements relatively often, works perfectly directly into my pi using the documentation on the Klipper wiki and I completely recommend using CAT5 cable with their twisted pair recommendations, I noticed that ribbon cables tended to have connection issues which wasn't surprising. Not much else to say other than it works because this is one of those products that either does or doesn't.

I wired mine up to an ESP32 via ESPHone and it works great controlling the motor on my bed that inclines it. After a little bit of math I was able to program a calculation of the angle of the bed and turn the motor off when it reached the desired angle. I was using an ultrasonic distance sensor but these are more accurate for this purpose.

If you don’t mind a little soldering, these are a decent deal. Helped get my Voron setup for input shaper quickly.

Used to setup input shaper on my 3D printer and worked perfectly. The price was good compared to other listings.

3 out of the five already stopped working mid sketch...they work for maybe 10 min and they just give up....
