A rotary encoder converts rotary switch movement to keyboard encoder outputs, gamepad encoder outputs, or output pulses that can be interpreted by keyboard encoders.

Offered by Groovy Game Gear, this gamepad encoder has built-in rotary support (see gamepad encoders entry).

The KADE series of Open Source/Open Hardware encoders have a Mechanical Rotary Joystick firmware that supports either one rotary stick with 6 player buttons + 7 admin buttons (either P1 or P2) or two rotary sticks with 3 player buttons each.

All of the KADE keyboard encoder-style outputs are customizable using the KADE Loader program.

Silverfox0786 has made two types of plug-and-play rotary joystick adapter boards for the miniArcade/minimus AVR.

One is a one-joystick, 6-button model (P1 or P2) the other is a two-joystick, 3-button model.

Rotary Joystick Interface to LS-30 harness

No longer available.

Offered by Ultimarc, this unit is a stand alone unit. It can convert two 12-position mechanical rotaries, and outputs a fixed set of keystrokes. It only encodes the rotary switch function on the joystick, not the up/down/left/right microswitch functions.

Offered by Hagstrom, this unit is capable of operating as a stand alone device or may be used with a keyboard encoder. Its are suitable for driving direct inputs on a keyboard encoder to produce a keystroke or keystrokes for each change of position of the rotary switch.

Druin's Rotary Interface

No longer available.

Offered by Druin, this was one of the first rotary encoders for the BYOAC crowd. You could download the plans and build your own board. It can convert two 12-position mechanical rotaries, and it needs to be connected to a separate keyboard encoder or gamepad encoder.
