The 555 timer IC is an integrated circuit that is popular used in a variety of timer pulse generation and oscillator applications. This NE555 frequency adjustable pulse generator Module utilizes the NE555 timer IC to generate pulses from about 4Hz to 1.3Khz which can be used for experimental development or driving a stepper motor it would be also a good choice for users learning&experiencing the analog RC circuits. Features: LED Output Indicator: Shows the output frequency clearly with LED light ON/OFF/Flashing Four optional frequency level: Low frequency (150Hz) Medium Frequency (50Hz1kHz) Mediumhigh frequency (1kHz10kHz) High frequency (10 kHz200 kHz). Fine adjustable duty ratio: the duty ratio and frequency cannot be adjusted respectively adjusting the duty cycle will change the frequency. Used as square wave generator for experimental development motor driver MCU pulse circuit control. Application: As a square wave signal generator generates a square wave signal used for experimental development Used to drive a stepper motor Generate adjustable pulse for MCU Generate adjustable pulse to control circuitry associated
