M274 360 Degree Rotary Encoder Sensor Module

The M274 360 Degree Rotary Encoder Sensor Module tracks rotation direction and position using the HW-040 mechanism, outputting 20 pulses per full revolution on the CLK pin. The DT pin indicates direction from phase difference between the two outputs. The rotary encoder runs on 3.3V to 5V DC with a 5-pin CLK DT SW interface.

The rotary encoder module knob also has a push switch on the SW pin activated by pressing down. A non-obvious point is that CLK and DT outputs need software debouncing in your sketch as there is no hardware debounce onboard. At 20 CPR, the m274 rotary encoder suits menu control but not precision angle measurement.

Students and developers use this rotary encoder for arduino project with Arduino IDE or MicroPython. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
