Product Parameters
- On – board NE555 chip;
- Single – channel signal output, and the output duty cycle is approximately a square wave of fifty percent;
- On – board adjustable resistor. Adjusting the resistance value can control the output frequency, and the default range is adjustable from 2K to 25KHz;
- Operating voltage: 5V – 12V;
- Board size: 29mm * 12mm;
Product Features
- The output is equipped with an LED indicator, making the presence or absence of output straightforward (the LED is on at low level, off at high level, and flashes when the frequency is relatively low);
- Optional output frequency range gears make the output frequency more continuously adjustable;
- Low-frequency gear: 1Hz – 50Hz
- Medium-frequency gear: 50Hz – 1kHz
- Medium-high-frequency gear: 1kHz – 10kHz
- High-frequency gear: 10kHz – 200kHz
- The output duty cycle can be fine – tuned. The duty cycle and frequency are not adjustable separately, and adjusting the duty cycle will change the frequency;
- The output frequency is adjustable: The period T = 0.7 (RA + 2RB) C. RA and RB are adjustable from 0 to 10K; C = 0.001UF in the low – frequency gear; C = 0.1UF in the medium – frequency gear; C = 1UF in the medium – high – frequency gear; C = 100UF in the high – frequency gear; When powered by 5V, the output current is about 15mA, and when powered by 12V, the output current is about 35mA. The power supply voltage range is 5V – 15VDC.
