NEW Stepper motor driving NE555 pulse frequency duty cycle adjustable module square wave signal generator |

Scope of application of this module:

The 1. is used as a square wave signal generator to generate square wave signals for experimental development.

The 2. is used to generate square wave signals driving the stepper motor driver.

3. generate adjustable pulse for MCU use.

4. generate adjustable pulses to control the relevant circuits.

Two, brief description:

1, size: 3.1CM*2.2CM

1, the main chip: NE555;

2, input voltage: 5V-15VDC. When 5V is supplied, the output current can be around 15MA. When 12V is supplied, the output current can be around 35MA.

3, input current: more than 100MA

4, output amplitude: 4.2V V-PP to 11.4V V-PP. (depending on the input voltage, the output amplitude will be different).

5. Maximum output current: > 15MA (5V supply, V-PP greater than 50%), > 35MA (12V supply, V-PP greater than 50%).

Three advantages:

1. Output with LED instructions, there is no output directly clear (low-level LED quantity, high-level LED off, low frequency LED flashing);

2, the output frequency range is optional to make the output frequency more continuous and adjustable.

Low frequency gear: 1Hz ~ 50Hz

Intermediate frequency: 50Hz ~ 1kHz

Medium high frequency gear: 1KHz ~ 10kHz

High frequency gear: 10kHz ~ 200kHz

3. Output duty cycle can be fine-tuned, duty cycle and frequency are not respectively adjustable, adjusting duty cycle will change the frequency;

4, the output frequency can be adjusted.

Periodic T=0.7 (RA+2RB) C

RA and RB are 0-10K adjustable.

C=0.001UF at low frequency.

C=0.1UF for intermediate frequency.

Medium and high frequency C=1UF;

The high frequency gear is C=100UF, so the frequency of the waveform can be calculated by the buyer himself.
