This 5V To 15V NE555 is a Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator. The output frequency range is selectable.
- Module is used as a square wave signal generator generates a square wave signal used for experimental development.
- To drive a stepper motor for generating a square wave drive signal.
- Adjustable pulse generated for use by MCU.
- Adjustable pulse generation, control circuitry associated.
- The main chip: NE555.
- Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can be around 35MA.
- The input current: 100MA
- The output amplitude: 4.2V V-PP to 11.4V V-PP. (Different depending on the input voltage, the output amplitude will be different)
- The maximum output current: 15MA (5V power supply, V-PP greater than 50%), 35MA (12V power supply, V-PP greater than 50%)
- The output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes).
- The output level selectable frequency range, the output frequency is more continuously adjustable: 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
- The output frequency is adjustable:
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. Introduced in 1971 by Signetics, the 555 is still in widespread use due to its ease of use, low price, and stability. It is now made by many companies in the original bipolar and also in low-power CMOS types.
This module can be used as a square-wave signal generator. It generates square wave signals used for experimental development. It also generates square wave signal driving motor drive. With adjustable pulses generated for use by the MCU and adjustable pulse control related circuits.
