Let op: door tolerantie van de componenten op de module kan de min/max frequentie afwijken!

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 development. Also, use to drive a stepper motor for generating a square wave drive signal.

The output duty cycle can fine-tune. 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.

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 adjustable pulse, to control circuitry associated.

Features :

1. Generate an adjustable pulse for MCU.
2. Generate an adjustable pulse, to control circuitry associated.
3. The output current can be 15 MA around; when 12V power supply, the output current can 35 MA around
4. Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes).
5. Max Output Current: >= ≥15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
