- Application: 1. Used as a square wave signal generator to produce square wave signals for experimental development. 2. Used to generate a square wave signal to drive a stepper motor driver. 3. Generates adjustable pulses for use by the MCU. 4. Generate adjustable pulses to control related circuits. Specification: Size: 31*22mm, Weight: 7g Main Chip: NE555 Input voltage: 5V-15VDC When power supply is 5V, the output current can be 15 MA around. When power supply is 12V, the output current can 35MA around. Input current:> = 100MA Output amplitude: 4.2V V - PP to 11.4V V - PP (Different input voltage, the output amplitude will be different) Max output current: ≥ 15MA (5V power supply, V-PP greater than 50%), ≥ 35MA (12V power supply, V-PP greater than 50%). Feature: 1. High level, LED will off. Low frequency, the LED flashes. 2. Output frequency range can be selected, so that the output frequency is more continuously adjustable. -Low frequency: 1Hz~ 50Hz -Medium frequency: 50Hz~1kHz -Medium-high frequency: 1KHz~10kHz -High frequency: 10kHz~200kHz 3. Output duty cycle can be fine-tuned, duty cycle and frequency are not separately adjustable, adjust the duty cycle will change the frequency. 4. The output frequency is adjustable Cyclical T=0.7(RA+2RB)C RA, RB is 0-10K adjustable -Low frequency: C=0.001UF -Medium frequency: C=0.1UF -Medium-high frequency: C=1UF -High frequency: C=100UF So the frequency of the waveform can calculate by buyer.
