Introduction
Product Parameters
- Size: 40mm * 20mm;
- Function: Generates square waves or rectangular waves of different frequencies;
- Power supply: Input voltage 5 – 12VDC. When powered by 5V, the output current can be around 10mA; when powered by 12V, the output current can be around 30mA;
- Frequency: 5 frequency segments (measured values)
- J1 gear: 0.6Hz – 25Hz
- J2 gear: 7Hz – 300Hz
- J3 gear: 50Hz – 2.5kHz
- J4 gear: 350Hz – 6.6kHz
- J5 gear: 6.7kHz – 180kHz
- Adjustable duty cycle range: 0.4 – 0.99
- LED output indication: The LED lights up at low level and goes out at high level. The speed of LED flashing indicates the change of frequency output. In addition to selecting different frequency segments with jumpers, RV1 adjustment can adjust the frequency. The flashing of the LED during adjustment can be regarded as the corresponding frequency change with the adjustment change;
- Input current: ≥100mA;
- Output voltage: 4.2V – 11.4V peak (varies with supply voltage);
- Output frequency calculation formula: Period T = 0.7 (Ra + 2Rb) C. Ra and Rb are adjustable from 0 to 10K;
- Input: VCC, GND. Output: VCC, OUT, GND. Here, the input voltage is consistent with the output, which is for the convenience of users and can be used for subsequent power supply. OUT is the output frequency signal.
Precautions:
When using jumper caps to change the frequency, please power off first, and then power on again after the jumper caps are connected.
