MIKROE Rotary R Click

Rotary R Click carries a 15-pulse incremental rotary encoder with detents surrounded by a ring of 16 red LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS SCK MISO MOSI). Rotary R Click can be used with either a 3.3V or 5V power supply.
