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
- Input Voltage:5–15V DC
- Output Voltage: 4.2V V-PP to 11.4V V-PP(depends on input voltage)
- Input current:>=100MA
- Maximum output current:Ranges from >=15MA (when 5V power supply, V-PP greater than 50%) to >=35MA (when 12V power supply, V-PP greater than 50%)
- Frequency Range:~1Hz to 200KHz (depends on duty cycle)
- Duty Cycle:Adjustable with potentiometer (5–95%)
- Size:31mm * 22mm
- Weight: 7g
- Pulse signal generation
- LED blinking tests
- Tone generation
- Used to drive a stepper motor for generating a square wave drive signal.
