NE555 TP354 Square Wave Pulse Module 50Hz-6KHz 0.8Hz-60Hz Frequency Adjustable Module Oscillator Output Signal Source

Product selling point:

1: Wide range of applications

2: Small size

3: Simple to use

4: stable performance

5: Two adjustment ranges are optional: L version is 0.8Hz-60Hz; H version is 50Hz-6kHz

?

Function Description:

1: The output terminal of the output square wave signal, the amplitude is approximately equal to the input voltage.

2: The output duty cycle is not adjustable, and the duty cycle of the output signal is basically stable (50%-65%) during the frequency adjustment process.

3: Frequency is adjusted by built-in multi-turn potentiometer, adjustment range: L version is 0.8Hz-60Hz; H version is 50Hz-6kHz

4: 3P 2.54mm pin header

?

Power supply:

The power supply voltage is DC 5V-15V, and the no-load current is about 3mA.

Output drive current:

The output circuit is capable of sinking or sourcing up to 200 mA. Action is specified as supply

5V to 15V. When using a 5 V supply, the output levels are compatible with TTL inputs.

?

Use:

Used as a signal source in a circuit;

?

Instructions:

1. Input power to work;

2. Terminate the power supply filter capacitor with 0.1uf, which is more stable.

3. Adjust the potentiometer clockwise to increase the frequency, and adjust the potentiometer counterclockwise to decrease the frequency.

4: Size: 14* 10.5 * 7.4mm (very small)

5: Weight: 1.4g

?

Notice:

1. The above parameters are measured at 5V, other voltages may vary.

2. This product is not a precision circuit and is not suitable for high precision.

?

Package list:

1* Frequency adjustable signal generator
