NE555 Pulse Signal Generator (For driving stepper, servo)

Description Purpose: Generate a square wave signal for experimental development use. Generate a square wave drive signal for driving steppers Generate adjustable pulse for MCU. Generate adjustable pulse for control-related circuit. Features: Size: 3.1CM * 2.2CM the main chip: NE555; 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; 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%) Advantages: Output with LED indication, there is no output straightforward (LOW LED quantity, high LED off, LED blink rate is relatively low); 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 You can fine-tune the output duty cycle, 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; At low frequencies file C = 0.001UF; Medium frequency 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 Documentation schematic, usage guide please see on this page.
