No knobs as advertised
Great little encoders but didnt come with knobs as described

Hmm. This product could use a deep socket nut so it could be built into 3/8" front panel hole. Am improvising. It will work with an embedded microcontroller and act as a coarse sweep switch on an oscilloscope where the micro generates the sweep waveforms. It is elegant !

I am building a robot lawn mower and use these as position sensors with arduino. work great!

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.

The encoder caps were extremely scratched up. Also not a single piece of foam, everything is just loose.

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
