NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator

Description

• Generate adjustable pulse for MCU
• Generate adjustable pulse, to control circuitry associated
• Main chip: NE555
• Input Voltage: 5V-15V DC. when power supply is 5 V , 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
• Unit price given
