CHENJ KY-040 Rotary Encoder Module Brick Sensor Development Board For Arduino

CHENJ. Features: 100 new and high quality. Material: Electronic components PCB. Size: About 31 x 19 x 29mm 1.22 x 0.75 x 1.14. Main color: Black. Working voltage: 5V. Pulse circle: 20. By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer count, this rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. Package Included: 1 x Rotary Encoder Module Brick Sensor Development Board For Arduino.
