NE555 Pulse Frequency signal Generator

The NE555 Pulse Frequency Signal Generator, is an NE555-timer based module that is used to create adjustable square wave drive signals.

Key Features:

• Variable frequency and duty cycle
• Onboard potentiometers
• NE555 timer IC based
• LED indicator: low level; LED on, High level; LED off and low frequency; LED flashes.
• Generate an adjustable pulse for microcontrollers.
• Generate an adjustable pulse, to control circuitry associated.
• Output frequency range gear is selectable, so output frequency is continuously adjustable;
  Low-frequency gear: 1Hz ~ 50Hz
  Medium frequency gear: 50Hz ~ 1kHz
  Medium and high frequency: 1KHz ~ 10kHz
  High frequency gear: 10kHz ~ 200kHz
