Description Description&Previewshipping&policy NE555 Pulse Frequency Duty Cycle Square Rectangular Wave Signal Generat Racg DESCRIPTION: Description: 100% brand new and high quality Module Scope: -Used as a square wave signal generator produces a square wave signal for the experimental development use. -Used to generate the square wave signal to drive a stepper motor drive. -Produce adjustable pulse for the MCU to ue. -Generating adjustable pulse to control the associated circuits. Features: -Size: 2.8CM * 3.6CM -The main chip: NE555; -Input voltage: 5V-15VDC. 5V power supply, the output current can about 15MA; 12V power supply, the output current can be so 35MA; -Input Current: ? 100MA -Output amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the output amplitude is not the same) -Maximum output current:? 15MA (5V power supply, V-PP greater than 50%), ? 35MA (12V power supply, V-PP greater than 50%) Advantages: -Output with LED indication, there is no output LED quantity (low straightforward, high level LED off relatively low frequency LED flashes); -Output frequency range grade optional continuously adjustable output frequency; -Low-frequency stall: 1Hz ~ 50Hz -IF stall: 50Hz ~ 1kHz -In the high-frequency stall: 1KHz ~ 10kHz -High-frequency stall: 10kHz ~ 200kHz -the output duty cycle can fine-tune the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency -the output frequency is adjustable; -Cycle T = 0.7*(Ra + 2*Rb)*C -Ra, Rb:0-10K adjustable; -LF gear C = 0.001UF; -IF file C = 0.1UF; -In the high-frequency file C = 1UF;, -High-frequency gear C = 100UF, the waveform frequency buyers can own calculations. NOTE:Output duty cycle can fine-tune the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency Package Included: 1PCS X NE555 Duty Cycle and Frequency Adjustable Module Square Wave Preview: Thank you for your purchase Problems?
