Feature:
 
1. Used as a square wave signal generator to generate square wave signals for experimental development.
2. Used to generate a square wave signal that drives the stepper motor driver.
3. Generate adjustable pulses for use by the MCU.
4. Generate adjustable pulses to control the associated circuitry.
 
Description:
 
1. Size: 3.5CM * 4.6CM
1. The main chip: LM358;
2. Input voltage: 5V-12VDC.
3. Input current: ≥100MA;
4. The output amplitude: close to the input voltage;
5. The frequency adjustment range: 0.07HZ-2KHZ (that is, the cycle is about 0.45 milliseconds to 15 seconds)
6. Duty cycle adjustment range: 0% to 100% (high level / period);
7. Output current: plate with 9012 triode, so the driving ability is relatively strong, the output current can be up to 500MA, the output can directly drive small relay or small motor;

Frequency adjustment method:
 
There are 4 shorting caps on the board to choose the frequency:
Insert 0 short-circuit caps, that is, all 4 short-circuit caps are removed, which is high frequency, and the period is adjusted to 0.3 seconds;
Insert a short-circuit cap, the period can be adjusted to about 4 seconds;
Insert 2 short-circuit caps, the period can be adjusted to about 7 seconds;
Insert 3 short-circuit caps, the period can be adjusted to about 10 seconds;
Insert 4 short-circuit caps, the period can be adjusted to about 15 seconds;

Package includes:

3 x NE555 Pulse Module
