How to Use

In the case of working with a MCU:

  • VCC : 3.0V ~ 5.3V
  • GND : power supply ground
  • SW : MCU.IO (encoder button status)
  • SIB : MCU.IO (output status)
  • SIA : MCU.IO (output status)


Connect the SIA, SIB, SW pins to the CH0, CH1, CH2 of logic analyser respectively, then power the module.

When clockwise rotating the encoder, the output waveform looks like:

When anti-clockwise rotating the encoder, the output waveform looks like:

When pressing the encoder button, the output waveform looks like:
