Encoder compatible with BeableBone Blue encoder inputs

[jco...@gmail.com]

The BeagleBone Blue has connectors for four quadrature encoder inputs.  I am looking for encoders that are compatible with these inputs.  It is surprisingly hard to find these.  Any suggestions?

I am looking for wheel encoders,  to be mounted for example on an axis.

The key problem is that the supply voltage provided in the 4 pin JST connectors for the encoders is only 3.3V.  Many encoders,  such as this one Rotary Encoder - 200 P/R (Quadrature) - COM-10932 - SparkFun Electronics require 5V or higher.
