NE555 pulse frequency adjustable duty cycle square wave module rectangular wave signal generator stepper motor driver

First, this module Scope:
1. is used as a square wave signal generator generates a square wave signal for experimental development to use.
2. is used to generate drive stepper motor drives a square wave signal.
3. adjustable pulse generation for MCU to use.
4. generates an adjustable pulse, the control-related circuit.

Second, a brief description:
1, Size: 3.1CM * 2.2CM
1, the main chip: NE555;
2, the input voltage: 5V-15VDC. 5V supply, the output current can be about 15MA; when 12V power supply, the output current can be about 35MA;
3, the input current: ≥100MA
4, the output amplitude:. 4.2V V-PP to 11.4V V-PP (different depending on the input voltage, the output amplitude will be different)
5, the maximum output current: ≥15MA (5V supply, V-PP greater than 50%), ≥35MA (12V power supply, V-PP greater than 50%)

Advantages:

1, the output with LED indication, there is no output straightforward (low level LED quantity, high LED off, LED blinks when the frequency is low);

2, grade selectable output frequency range, the output frequency is more continuously adjustable;
LF file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High frequency gear: 1KHz ~ 10kHz
High frequency profile: 10kHz ~ 200kHz

3, the output duty cycle can be fine-tuning, duty cycle and frequency are not separately adjustable, adjusting the duty cycle will change the frequency;

4, the output frequency is adjustable;
Cycle T = 0.7 (RA + 2RB) C

RA, RB for 0-10K adjustable;

At low frequencies stalls C = 0.001UF;
IF stalls when C = 0.1UF;
High-frequency gear C = 1UF;
When high-frequency gear C = 100UF, therefore frequency waveform buyers can own calculations.

Package Included:
1pcs * NE555 stepping motor driver module
