NE555 Duty Cycle and Frequency Adjustable Module Square Wave Pulse generator PCB Module Scope 1. Used as a square wave signal generator produces a square wave signal for the experimental development use. 2. Used to generate the square wave signal to drive a stepper motor drive. 3. Produce adjustable pulse for the MCU to use. 4. Generating adjustable pulse to control the associated circuits. A brief description 1. Size: 3.5CM * 3.6CM 2. The main chip: NE555; 3. Input voltage: 5V-15VDC. 5V power supply, the output current can about 15MA; 12V power supply, the output current can be so 35MA; 4. Input Current: ? 100MA 5. Output amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the output amplitude is not the same) 6. Maximum output current: ? 15MA (5V power supply, V-PP greater than 50%), ? 35MA (12V power supply, V-PP greater than 50%) Advantages 1. Output with LED indication, there is no output LED quantity (low straightforward, high level LED off relatively low frequency LED flashes); 2. 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 3. the output duty cycle can fine-tune the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency 4. 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 FREE! Sellers: Add a FREE map to your listings. FREE!
