The I2C Quad Rotary Encoder breakout allows you to read up to 4 encoders for big builds with lots of twisty interfaces. You can solder in any four ‘standard’ PEC11-pinout rotary encoders with or without a push-switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C.
The Adafruit I2C Quad Rotary Encoder Breakout guide has everything you need to get started with using the breakout. There’s pages for overview, pinouts, CircuitPython, Arduino and resources for download.
