potentiometru encoder rotativ cu buton ky-040 Keyes arduino avr stm pic

Description: This device combines absolute encoder with integrated reset switch and pull-up resistors. Compact and simple to use. Pin description: CLK - equivalent to output A in regular encoder DT - equivalent to output B in regular encoder GND - equivalent to output C in regular encoder SW - reset switch + (VCC) - positive supply to the unit, 100% Brand new and high quality. Material: Electronic components + PCB Size: About 31 * 19 * 29mm / 1.22" * 0.75" * 1.14" 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 KY-040 rotary decoder module
