WMYCONGCONG 8 Pcs KY-040 360 Degree Rotary Encoder Module with Knob Cap for Arduino Micro Controller Use

These are actually quadrature encoders. They function well; however, none of the documentation matches the labeling on the device. With a little trial and error you can hook them up and they work great. No switch bounce that is normally found in mechanical encoders. They are very inexpensive.

These are great for the money. They feel fine, comes with knobs, washers, and nuts. I'm running mine on the 3.3v rail of my pi zero 2w, it works just fine if you don't have the 5v available.

I used these along with a Raspberry Pi Pico W to create a button panel for sim racing. I use three rotary encoders to control brake bias and front/back anti roll bar. Works like a charm.

Great encoders, these have the two resistors on the back side, I’ve had previous encoders that only had a single resistor and they gave me issues with my menu system. These seem to solve the problem for my spot welder. Great product

As yet untested but appear to be of good quality. Quick delivery with great packaging.

Works great with Arduino!

Documentation for this is not with the product but it's easy to find online. works well. No issues with speed.

One click is registered as two. Maybe I'm using it wrong or have the wrong idea of how a rotary encoder should work but I had to account for that in the software I'm writing that reads the value of the encoder.The knobs look good and match the knobs of the potentiometers I have. They're easy to wire up and there are quite a few Python modules for reading the values.
