Electronic module Ne555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Rectangular Wave Signal Generator Module Stepper Motor Drive

1. Used as a Square Wave Signal Generator to Generate Square Wave Signals for Experimental Development.

2. Used to Generate Square Wave Signal for Driving Stepper Motor Driver.

3. Generate Adjustable Pulse for MCU.

4. Generate Adjustable Pulse and Control Related Circuits.

2. Brief Description:

1. Size: 3.1cm * 2.2cm

1. Main Chip: Ne555;

2. Input Voltage: When the Power Supply Is 5v-15vdc.5v, the Output Current Can Be about 15Ma; When the Power Supply Is 12V, the Output Current Can Be about 35ma;

3. Input Current: ≥ 100mA

4. Output Amplitude: 4.2V V-PP to 11.4V V-PP.(the Output Amplitude Will Be Different Depending on the Input Voltage)

5. Output Current: ≥ 15Ma (5V Power Supply, V-PP Greater than 50%),≥ 35ma (12V Power Supply, V-PP Greater than 50%)

Three Advantages:

1. the Output Is Indicated by LED, and Whether the Output Is Directly Clear (the Led Quantity at Low Level, the High Level LED Is off, and the LED Flashes When the Frequency Is Relatively Low);

2. the Output Frequency Range Is Optional, Making the Output Frequency More Continuously Adjustable;

Low Frequency: 1Hz to 50Hz

Intermediate Frequency: 50Hz ~ 1KHz

Medium and High Frequency Range: 1KHz to 10KHz

High Frequency Range: 10KHz to 200KHz

3. the Output Duty Cycle Can Be Fine-Tuned. the Duty Cycle and Frequency Are Not Respectively Adjustable. Adjusting the Duty Cycle Will Change the Frequency;

4. Adjustable Output Frequency;

Period T = 0.7 (Ra + 2RB)CRA,RB Is 0-10K Adjustable;

C = 0.001UF in Low Frequency Range;

If C = 0.1UF;

Medium and High Frequency Range C = 1UF;
