Description: NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator Specifications: As a square wave signal generator,generates a square wave signal used for experimental development. Used to drive a stepper motor for generating a square wave drive signal. Generate adjustable pulse for MCU. Generate adjustable pulse,to control circuitry associated. Size: 31mm x 22mm Main Chip: NE555 Input Voltage: 5V-15V DC. when power supply is 5 V , the output current can be 15 MA around; when 12V power supply, the output current can 35 MA around Input Current: >=100 MA Output Amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different) Maximum Output Current: >=15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%) Output with LED indication(low level ,LED will on; high level,LED will off;low frequency, the LED flashes) The Output Frequency Range: Selectable: LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High-frequency file: 1KHz ~ 10kHz HF file: 10kHz ~ 200kHz The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable;adjusting the duty cycle will change the frequency What you will receive: 1 x NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator
