The scope of application of this module: 1.As a square wave signal generator, generate square wave signals for experimental development and use. 2.Used to generate a square wave signal that drives a stepper motor driver. 3.The adjustable pulse is used by the MCU. 4.Generate adjustable pulses to control the associated circuitry. Parameter Size: 35x33mm; 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%) Features 1.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); 2.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. 3.The output frequency is adjustable; Cycle T=0.7(RA+2RB)C VR1, VR2 are 0-10K adjustable; Low frequency, C=0.001UF; Medium frequency, C=0.1UF; Medium-high frequency , C=1UF; High frequency, C=100UF, so the user can calculate the frequency of the waveform. Package Included: 1pcs NE555 Pulse Module See more
