Description:

Size: 31mm * 22mm;
      

Main chip: NE555;
      

Input Voltage: 5V-15VDC. when power supply is 5V, the output current can be 15MA around;when 12V power supply, the output current can 35MA around;
      

Input current: >=100MA
      

Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
      

Maximum output current: >=15MA (5V power supply, V-PP greater than 50%), 
>=35MA (12V power supply, V-PP greater than 50%)
Output with LED indication (low level,LED will on; high level, LED will off; low frequency, the LED flashes);
The output frequency range is selectable:
LF file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High-frequency file: 1KHz ~ 10kHz
HF file: 10kHz ~ 200kHz
The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable;adjusting the duty cycle will change the frequency;

The output frequency is adjustable:
      
      Period T = 0.7 (RA +2 RB) C
      RA, RB is 0-10K adjustable;
      Low profile when C = 0.001UF;
      IF stalls C = 0.1UF;
      High-frequency file C = 1UF;
      HF stalls C = 100UF;
      so buyers can calculate the frequency of the waveform.
      Application:

As a square wave signal generator, generates a square wave signal used for experimental development.
      

Used to drive a stepper motor for generating a square wave drive signal.
      

Generate adjustable pulse for MCU.
      

Generate adjustable pulse, to control circuitry associated.
