Description
1. Size:3.5CM * 4.6CM
1. The main chip:LM358;
2. Input voltage:5V-12VDC.
3. Input current:≥100MA;
4. The output amplitude:close to the input voltage;
5. The frequency adjustment range:0.07HZ-2KHZ (that is, the cycle is about 0.45 milliseconds to 15 seconds)
6. Duty cycle adjustment range:0% to 100% (high level / period);
7. Output current:plate with 9012 triode, so the driving ability is relatively strong, the output current can be up to 500MA, the output can directly drive small relay or small motor;
Frequency adjustment method
There are 4 shorting caps on the board to choose the frequency
Insert 0 short-circuit caps, that is, all 4 short-circuit caps are removed, which is high frequency, and the period is adjusted to 0.3 seconds;
