10pcs NE555 Pulse Frequency Duty Cycle Square Wave Rectangular Wave Signal Generator Adjustable 555 Board NE555P Module

Features:

 

-Size: 3.5CM * 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
