Description

This little PCB is a very versatile 555 timer circuit that can be easily adjusted for most any purpose that 555 Chip can be used for :

  • Input current: >=100MA
  • Output amplitude: 4.2V V-PP at 5v supply  ;   or 11.4V V-PP at 12v Supply.
  • 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-ON ; high level,LED-OFF );
  • The output frequency range is selectable:
    • 1Hz ~ 50Hz
    • 50Hz ~ 1kHz
    • 1KHz ~ 10kHz
    • 10kHz ~ 200kHz
  • The output frequency and duty cycle are interdependent : changing one will also affect the other – just like in any standard 555 timer circuit …

    • 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 user can calculate the frequency and the waveform.

     

    The circuit can be easily modified for higher frequencies as well as for ultra-long delay timer function…
