Product description ne555 pulse frequency duty cycle adjustable module square wave signal generator is 5 v square wave signal generator. It generates a square wave signal used for experimental use to, Development. Also drive a stepper motor for generating a square wave drive signal. The output duty cycle can fine, Tune. Duty cycle and frequency is not adjusting the, Separately adjustable duty cycle will change the frequency. The output frequency is adjustable period t = 0. 7 ra, 2 rb rb is, C ra 0, 10k adjustable, Low profile when c = 0. 001uf, If stalls c = 0. 1uf, High, Frequency file c = 1uf, Hf stalls c = 100uf, So buyers can calculate the rate at which the waveform. Features generate an adjustable pulse for mcu. Generate an adjustable pulse, To control circuitry associated. The delivered current can be 15 ma around, The output current can, When 12v power supply 35 ma around output with led indication low level, Led will on, Led will, High level off, The led, Low frequency flashes . Max output current >= 15ma 5v power supply, V, Pp greater than 50%, >=35ma 12v power supply, V, Pp greater than 50% application as a square wave signal generator generates a square wave signal used for experimental development. Used to drive a stepper motor for generating a square wave drive signal. Generate an adjustable pulse for mcu. Generate an to control, Adjustable pulse circuitry associated. Includes a single unit x ne555 pulse frequency duty cycle adjustable module square wave signal generator
