Rotary click with its LED ring is a perfect solution for implementing an input knob into your design (in contrast to a potentiometer, a rotary encoder can be spun round continuously). A single rotation is divided into 15 discrete steps. The encoder outputs A and B signals (out of phase to each other). The knob is also a push-button outputted through the interrupt line. The LED ring are controlled through the SPI interface.
In addition to the SPI lines (CS, SCK, MISO, MOSI), Rotary clicks have three additional lines for outputting the Encoder info: ENCB OUT, ENCA OUT and SW (in place of the standard AN, RST and INT pins, respectively).
All Rotary click boards can be used with either a 3.3V or 5V power supply. The configuration is set up with an onboard jumper (zero ohm resistor). By default, it’s set to 3.3V
