3Pcs 0.8Hz-60Hz Adjustable Signal Generator TP354 NE555 Module Square Wave Pulse Generator Oscillator Output Signal Source (0.8Hz-60Hz)
The output terminal of the square wave signal has an amplitude approximately equal to the input voltage.
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.
The frequency is adjusted through a built-in multi turn potentiometer, with a range of 0.8Hz-60Hz for the L version; The H version is 50Hz-6kHz
The power supply voltage is DC 5V-15V, and the no-load current is about 3mA.
The output circuit is capable of absorbing or providing up to 200 mA of current. Operation designated as supply
