NE555 Pulse Frequency Duty Cycle Adjustable Module

NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is a 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor for generating a square wave drive signal.

The output duty cycle can fine-tune. The duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency.

The output frequency is adjustable:

1. Period T = 0.7 (RA +2 RB) C
2. RA, RB is 0-10K adjustable;
3. Low profile when C = 0.001UF;
4. IF stalls C = 0.1UF;
5. High-frequency file C = 1UF;
6. HF stalls C = 100UF;
7. So buyers can calculate the frequency of the waveform.
