Adafruit I2C Quad Rotary Encoder Breakou

Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little detents for tactile feedback. But, if you've ever tried to add encoders to your project you know that they're a real challenge to use: timers, interrupts, debouncing... This Stemma QT breakout makes all that frustration go away - and 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. Plug it in with a Stemma QT cable for instant rotary goodness, with any kind of microcontroller from an Arduino UNO up to a Raspberry Pi.
