NE555 pulse frequency adjustable duty cycle module stepper motor driver#XTW3333 Description First, the scope of this module: 1 is 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. Second, a brief description: 1, Size: 3.1CM * 2.2CM 1, the main chip: NE555; 2, 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; 3, the input current: ≥ 100MA 4, 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%) Three 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; LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High frequency file: 1KHz ~ 10kHz High-frequency file: 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; 4, the output frequency is adjustable; Cycle T = 0.7 (RA +2 RB) C RA, RB is 0-10K adjustable; At low frequencies file C = 0.001UF; IF file when C = 0.1UF; High frequency file C = 1UF; When high-frequency gear C = 100UF, so the frequency of the waveform buyers can own calculations. shipping list:1pcs NE555 pulse frequency adjustable duty cycle module stepper motor driver Payment We accept Paypal as the payment method.
