NE555 pulse module LM358 duty cycle frequency adjustable module square wave:
$1.78
Application scope:
1. Used as a square wave signal generator produces a square wave signal for the experimental development use.2. A square wave signal is used to produce a stepper motor-driven drive.3. Produce the adjustable pulse for MCU use.4. Generates the adjustable pulse to control the associated circuits. Descriptions:
1. The main chip: LM358.2. Input voltage: 5V-12VDC.3. The input current: ≥ 100MA.4. The output amplitude: close to the input voltage.5. The frequency adjustment range: 0.07HZ-2KHZ (also cycle in about 0.45ms to 15s).6. Duty cycle adjustment range: 0% to 100% (High / cycle).7. Output Current: strip 9012 transistor drive capability is strong, about 500MA output current, the output can directly drive small relays or small motors.
Frequency adjustment methods:
1. The board has four the shorting cap can select the frequency.2. Inserted 0 short-circuit cap, the longest cycle upwards to 0.3 s.3. Inserted one short-circuit cap, the longest cycle can be adjusted to about 4s.4. Inserted two short-circuit cap, the longest cycle can be adjusted to about 7s.5. Inserted three short-circuit cap, the longest cycle can be adjusted to about 10s.6. Inserted four short-circuit cap, the longest cycle can be adjusted to about 15s.7. Duty cycle adjustment range: 0% to 100% (High / cycle).8. Output Current: strip 9012 transistor drive capability is strong, about 500MA output current, the output can directly drive small relays or small motors.
