The Rotary G Click Board™ from MikroE features a 15-pulse incremental rotary encoder with detents, which is surrounded by a ring of 16 green LEDs. If the user wants to implement a precision input knob into the design, such a rotary Click Board™ will be a perfect solution. Every single rotation is divided into 15 discrete steps. The encoder output has A and B signals (out of phase to each other). The knob also works as a push-button to send an interrupt to the target board MCU. The 16 LED ring is controlled via SPI communication interface.
The Rotary G Click Board™ can be used with either a 3.3V or 5V power supply. Such a Click Board™ would be useful in controlling audio/video equipment and other similar electrical devices.
