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 use. -Generating adjustable pulse to control the associated circuits. 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
Package Included:
1PCS X NE555 Duty Cycle and Frequency Adjustable Module Square Wave
