نقد و بررسی اجمالی

ژنراتور سیگنال موج مربع قابل تنظیم فرکانس پالس بین 15Hz to 24KHz و دیوتیسایکل حدود 50 درصد

 is used as a square wave signal generator generates a square wave signal used for experimental development
 to drive a stepper motor for generating a square wave drive signal
 adjustable pulse generated for use by MCU
 adjustable pulse generation, control circuitry associated

:a brief description
 the main chip: NE555
 Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around

 the input current: 100MA
the output amplitude: 4.2V V-PP to 11.4V V-PP. (Different 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, V-PP greater than 50%)

:Technical Specifications

 The main chip: en555
Input voltage: 5V-12VDC
The input current: ≥ 100MA
The output amplitude: close to the input voltage
The frequency adjustment range: 0.07HZ-2KHZ (also cycle in about 0.45ms to 15s
Duty cycle adjustment range: 0% to 100% (High / cycle
 Output Current: strip 9012 transistor drive capability is strong, about 500MA output current, the output can directly drive small relays or small motors

:Advantages

 the output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes
the output level selectable frequency range, the output frequency is more continuously adjustable
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

 the output frequency is adjustable Period T = 0.7 (RA +2 RB) C

RA, 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
