DollaTek 5Pcs NE555 Pulse Frequency Duty Cycle Adjustable Modules Square Wave Signal Generator
DollaTek 5Pcs NE555 Pulse Frequency Duty Cycle Adjustable Modules Square Wave Signal Generator
Features: 1. As a square wave signal generator, generates a square wave signal that is used for experimental development. 2. Used to drive a stepper motor to generate a square wave driving signal. 3. Generate an adjustable pulse for the MCU. 4. Generate an adjustable pulse to control the associated circuit. 5. Size: 31mm x 22mm 6. Main chip: NE555 7. Input voltage: 5V-15V DC. When the power supply is 5V, the output current can be 15MA. With 12V power supply, the output current can be 35 MA 8. Input current: ≥100 MA 9. Output amplitude: 4.2 V V-PP to 11.4 V V-PP. (Different input voltage, the output amplitude is different) 10. Maximum output current: ≥15mA (5V power supply, V-PP greater than 50%), ≥35mA (12V power supply, V-PP greater than 50%) 11. Output with LED display (low level, LED lights up; high level, LED turns off; low frequency, LED flashes) 12. The output frequency range is selectable: LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High frequency file: 1kHz ~ 10kHz RF file: 10kHz ~ 200kHz 13.The output duty cycle can be fine-tuned. Duty cycle and frequency cannot be set separately. Adjusting the duty cycle changes the frequency. Package contents: 5 x NE555 pulse frequency duty cycle adjustment module
