UPDATE: Check out the new version with pull-up resistors
I designed this simple breakout board in KiCad to make it easier to put a rotary encoder on a breadboard. The KiCad symbol and footprint for the SparkFun rotary encoder was created by mcous on GitHub. I used an updated version with corrected pin numbering.
Here are the rotary encoders that I’ve verified to fit:
- SparkFun Rotary Encoder (COM-09117)
- Bourns Inc. PEC12R-4220F-S0024 (Digi-Key)
The design files are available on GitHub:
The board is shared on OSH Park:
