NOYITO NE555 Pulse Module Rectangular Square Wave Signal Generator 1Hz-200kHz Frequency Duty Cycle Adjustable DC5-15V

The scope of application of this module: As a square wave signal generator, generate square wave signals for experimental development and use. Used to generate a square wave signal that drives a stepper motor driver. The adjustable pulse is used by the MCU. Generate adjustable pulses to control the associated circuitry. , The main chip: NE555; input voltage: 5V-15VDC. 5V power supply, the output current can be around 15MA; 12V power supply, the output current can be around 35MA; input current: 100MA;, Output amplitude: 4. 2V V PP to 11. 4V V-PP. (Depending on the input voltage, the output amplitude will be different); The maximum output current: 15MA (5V power supply, V-PP greater than 50%), 35MA ( 12V power supply, when V-PP is greater than 50%), Output with LED indication, there is no output, visually visible (low LED when the high; when the high level LED off; when the frequency is relatively low, the LED flashes);, The output frequency range grade is optional, making the output frequency more continuously adjustable; low frequency range: 1Hz-50Hz, medium frequency range: 50Hz-1kHz, medium-high frequency range: 1KHz-10kHz, high frequency range: 10kHz-200kHz.
