I. Scope of Application of This Module:
1. Used as a Square Wave Signal Generator to Generate Square Wave Signals for Experimental Development.
2. It Is Used to Generate the Square Wave Signal That Drives the Stepper Motor Driver.
3. Generate Adjustable Pulse for MCU to Use.
4. Generate Adjustable Pulse and Control Related Circuit.
2. Brief Description:
1. Size: 3.1cm * 2.2cm
1. Main Chip: Ne555;
2. Input Voltage: 5v-15vdc. 5V Power Supply, the Output Current Can Be about 15Ma; 12V Power Supply, 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. Maximum 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)C

Ra and Rb Are 0-10K Adjustable;

C = 0.001UF in Low Frequency Range;
If C = 0.1Uf;
Medium and High Frequency Range C = 1UF;
C = 100Uf at High Frequency, So Buyers Can Calculate the Frequency of the Waveform by Themselves.
