Description

1Hz-6Khz Adjustable Signal Generator DC 5V-15V Square Wave Generator Module NE555 50Hz-6Khz 0.8Hz-60Hz TTL Input Levels Output

Features: 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. list 1* Frequency adjustable signal generator
