1PCS NE555 Square Wave Duty Cycle and Frequency Adjustable Module L

• 1 This module is used as a square wave signal generator generates a square wave signal for experimental development to use.
  2 This module is used to generate drive stepper motor drives a square wave signal.
  3 It\'s adjustable pulse generation for MCU to use.
  4 It generates an adjustable pulse, the control-related circuit.
  description:
  1, Size: 2.9CM * 3.6CM
  1, the main chip: NE555;
  2, the input voltage: 5V-15VDC. 5V supply, the output current can be about 15MA; when 12V power supply, the output current can be about 35MA;
  3, the input current: ≥100MA
  4, the output amplitude:. 4.2V V-PP to 11.4V V-PP (different depending on the input voltage, the output amplitude will be different)
  5, the maximum output current: ≥15MA (5V supply, V-PP greater than 50%), ≥35MA (12V power supply, V-PP greater than 50%)
• Advantages:
  1, the output with LED indication, there is no output straightforward (low level LED quantity, high LED off, LED blinks when the frequency is low);
  2, grade selectable output frequency range (with jumper put option), the output frequency is more continuously adjustable;
  LF file: 1Hz ~ 50Hz
  IF file: 50Hz ~ 1kHz
  High frequency gear: 1KHz ~ 10kHz
  High frequency profile: 10kHz ~ 200kHz
  3
  The output frequency is adjustable;
  Cycle T = 0.7 (RA + 2RB) C
• RA, RB for 0-10K adjustable;
• At low frequencies stalls C = 0.001UF;
  IF stalls when C = 0.1UF;
  High-frequency gear C = 1UF;
  When high-frequency gear C = 100UF
