About KNACRO NE555 Pulse Generator Square Wave
Max. Output Current : 10mA (5V Power Supply ) 30mA (12V Power Supply); PCB Board Size :20 * 40mm Materials : FR-4, PCB;Main Color : Green, Black, Blue Net Weight : 11g Package Content: 1 x NE555 Pulse Module Frequency: J1: 0.6 ~ 25Hz J2: 7 ~ 300Hz J3: 50 ~ 2.5KHz J4: 350K ~ 6.6KHz J5: 6.7K ~ 180KHz Adjustable duty cycle range: 0.4-0.99 It is used as a square wave signal generator to enerate a square wave signal for experimental development use; For generating drive a stepper motor drive of the square wave signal; Adjustable pulse generated for the use of MCU; Generated adjustable pulse to control related circuit. With output indicator: LED on when low level, LED off when high level, LED flashed when low frequency; Output levels of frequency range is selectable, which is benefit for output frequency is continuously adjustable; LF level: 1Hz ~ 50Hz; IF level: 50Hz ~ 1kHz; High frequency level: 1KHz ~ 10kHz; HF level: 10kHz ~ 200kHz Input Current: ≥100ma Output Voltage: 4.2v-11.4v peak. With the power supply voltage variation The output frequency is calculated: Period T = 0.7 (Ra + 2Rb) c Ra, Rb is 0-10k adjustable. Input: VCC GND SHUCHU:. VCC OUT GND same output voltage and input voltage. OUT is the output frequency signal.
