This is an easy to use board that provides mounting of a rotary encoder and the debounce components for both the encoder portion and an optional switch, if your rotary encoder has a switch. The improved version provides Schmitt triggers on the encoder output in addition to the RC debounce.
I've always been frustrated with how hard it is to pick up a rotary encoder and just use it, either on a breadboard or in a final project. Rotary encoders just don't fit on a breadboard very well. To debounce it correctly for use with an Arduino or Teensy, one needs two capacitors and two resistors. In addition, many of the cheaper rotary encoders do not come with threads, leaving the builder to support it on a pcb, if you are lucky enough to fabricate one.
I designed this reusable module that works great on a both a breadboard and in a final project box. This module has two holes to mount the board on stands on a chassis. If you are using a rotary encoder that is threaded, then ignore the holes! There is a five pin header (2.54mm) that mounts easily on a breadboard; or solder wires directly to the board.
The A and B rotary encoder output can be directly used with and Arduino or Teensy. This module is 3v and 5v compatible.

I build modules because they are useful. Assembled in the Portland, OR (specifically the garage).
Midnight makers and engineers don't always have a lot of time; the modules save you time.
