NE555 Pulse Frequency Duty Cycle Adjustable Module Square Rectangular Wave Signal Generator Stepper Motor DriveItem NO.: NE555 pulse

NE555 Pulse Frequency Duty Cycle Adjustable Module

Applicable Scope:

1. Used as a square wave signal generator to generate square wave signals for experimental development.

2. Used to generate square wave signals that drive stepper motor drivers.

3. Generate adjustable pulses for MCU use.

4. Generate adjustable pulses and control related circuits.

Brief Description:

1. Main chip: NE555;

2. Input voltage: 5V-15VDC. When powered by 5V, the output current can be around 15MA; When powered by 12V, the output current can be around 35MA;

3. Input current: ≥ 100MA

4. Output amplitude: 4.2V V-PP to 11.4V V-PP (The output amplitude may vary 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%)

6. Size: 3.1CM * 2.2CM

Advantages And Characteristics:

1. Output with LED indication, whether there is an output directly clear (low level LED quantity, high level LED off, LED flashing when the frequency is relatively low);

2. Optional output frequency range and grade, making the output frequency more continuous and adjustable;

Low frequency range: 1Hz~50Hz

Medium frequency range: 50Hz~1kHz

Medium and high frequency range: 1KHz~10kHz

High frequency range: 10kHz~200kHz

3. The output duty cycle can be fine tuned, but the duty cycle and frequency are not separately adjustable. Adjusting the duty cycle will change the frequency;

4. Adjustable output frequency;

Cycle T=0.7 (RA+2RB) C

RA and RB are adjustable from 0-10K;

At low frequency range, C=0.001UF;

C=0.1UF in mid frequency range;

Medium and high frequency range C=1UF;

At high frequency, C=100UF, so buyers can calculate the frequency of the waveform themselves
