1, Size: 3.1CM * 2.2CM1, the main chip: NE555;2, Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around;3, the input current: 100MA4, the output amplitude: 4.2V V-PP to 11.4V V-PP. (Different depending on the input voltage, the output amplitude will be different)5, the maximum output current: 15MA (5V power supply, V-PP greater than 50%), 35MA (12V power supply, V-PP greater than 50%)The scope of this module:1 is used as a square wave signal generator generates a square wave signal used for experimental development.2 to drive a stepper motor for generating a square wave drive signal.3 adjustable pulse generated for use by MCU.4 adjustable pulse generation, control circuitry associated.Advantages:1, the output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes);2, the output level selectable frequency range, the output frequency is more continuously adjustable;LF file: 1Hz ~ 50HzIF file: 50Hz ~ 1kHzHigh-frequency file: 1KHz ~ 10kHzHF file: 10kHz ~ 200kHz3, the output duty cycle can fine-tune, duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency4, the output frequency is adjustable;Period T = 0.7 (RA +2 RB) CRA, RB is 0-10K adjustable;Low profile when C = 0.001UF;IF stalls C = 0.1UF;High-frequency file C = 1UF;HF stalls C = 100UF, so the frequency of the waveform buyers can own calculations
