10pcs/lot NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave 5V-12V Signal Ster Motor Driver NE555

10pcs NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave 5V-12V Signal Ster Motor Driver NE555

Feature: Is used as a square wave signal generates a square wave signal used for experimental development. To drive a ster motor for generating a square wave drive signal. Adjustable pulse generated for use by MCU. Adjustable pulse generation, control circuitry aociated. Descrtion: Size: 3.1CM * 2.2CM The main ch: NE555; Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around; 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%) Advantages: The output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED fes); 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: Period T = 0.7 (RA +2 RB) C RA, RB is 0-10K adjustable; Low profile when C = 0.001UF; IF stalls C = 0.1UF; High-frequency file C = 1UF; HF stalls C = 100UF, so the frequency of the waveform buyers can own calculations.
