NE555 Stepper Motor Driver Frequency Adjustable Module Duty Cycle Square Wave

£2.15
NE555 Stepper Motor Driver Frequency Adjustable Module Duty Cycle Square Wave 
 
Description:
1. Size : 3.1CM x 2.2CM
2. Main chip : NE555; 
3. Input voltage : 5V-15VDC. When 5V supply, the output current can be at around 15MA; when the 12V supply, the output current can be about 35MA; 
4. input current : ¡Ý 100MA
5. The output amplitude :. 4.2V V-PP to 11.4V V-PP ( different depending on the input voltage , the output amplitude will be different ) 
6. The maximum output current : ¡Ý 15MA (5V power supply , V-PP greater than 50%), ¡Ý 35MA (12V power supply , V-PP greater than 50% ) 
 
 
Advantages: 
1. The output with LED indication , there is no output straightforward ( low level LED volume, high LED off frequency is relatively low LED flashes ) 
 
2. The output frequency range of grades available, the output frequency more continuously adjustable ; 
Low Frequency: 1Hz ~ 50Hz
Medium Frequency: 50Hz ~ 1kHz
Medium and High frequency: 1KHz ~ 10kHz
High frequency: 10kHz ~ 200kHz
 
3. The output duty cycle can be fine-tuning, duty cycle and frequency are not adjustable , adjust the duty cycle will change the frequency ; 
The output frequency is adjustable ; 
Cycle T = 0.7 (RA +2 RB) C
RA, RB is 0-10K adjustable ; 
Low frequencies C = 0.001UF; 
Medium Frequency C = 0.1UF; 
Medium & High frequency file C = 1UF; 
High-frequency gear C = 100UF, 
 
Application: 
1. Be used as a square wave signal generator generates a square wave signal for experimental development use. 
2. Drives the stepping motor for generating a square wave drive signal. 
3. Adjustable pulse generated for MCU to use. 
4. Adjustable pulse generating control-related circuit.
