we've used them on all of our swerves, and started using them instead of pots for other functions like arm position and such, they've been very reliable for us.

111 has used them and has noticed some static issues as a warning though.

this year we had 4 on our bot, 1 on each side of the drive, and 1 on each sides bogey wheel. no issues with them

where did you mount them at? and how?

Im not 100% sure I understand how those work......

How do they actually measure the rotation?
I was thinking they are in contact with the rotating object? And then it just counts the rotation of its shaft? That would be a mechanical encoder then right?...those are magnectic encoders..how do they work?

sorry about all the questions,I dont do electronics(although now's a good time to learn i guess)
