Scope of this module: 1. Used as a square wave signal generator to generate square wave signals for experimental development. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4. Generate adjustable pulses to control related circuits. Specification: 1. Size: 29x36mm, fixed hole distance 22.5x30.5mm 2. Main chip: NE555 3. Input voltage: 5V-15VDC. When 5V power supply, the output current can be around 15MA; when 12V power supply, the output current can be around 35MA; 4. Module weight: 10g; 5. Input current:> = 100MA 6. Output amplitude: 4.2V V-PP to 11.4V V-PP. (The output amplitude will be different according to the input voltage) 7. Output current:> = 15MA (5V power supply, V-PP greater than 50%), ≥35MA (12V power supply, V-PP greater than 50%) Advantages 1. The output has LED indication, and it is clear whether there is output (LED quantity at low level, LED off at high level, LED flashes at low frequency) 2. The output frequency range can be selected (selected with a short-circuit cap) to make the output frequency more continuously adjustable; - Low frequency range: 1Hz ～ 50Hz - Intermediate frequency range: 50Hz ～ 1kHz - Middle and high frequency range: 1KHz ～ 10kHz - High frequency range: 10kHz ～ 200kHz 3. The output duty cycle can be fine-tuned, the duty cycle and frequency are not separately adjustable, adjusting the duty cycle will change the frequency; if you need a module with adjustable duty cycle and frequency, 4. The output frequency is adjustable; - Period T = 0.7 (RA + 2RB) C - RA and RB are adjustable from 0-10K; - C = 0.001UF at low frequency; - C = 0.1UF in the intermediate frequency range; - Medium and high frequency gear C = 1UF; - C = 100UF at high frequency, so the frequency buyer of the waveform can calculate it by himself. Please save this page as an instruction, if you need a circuit diagram, you can ask the buyer after taking another picture. 1. Applicable occasions: MCU learning, electronic competition, product development, taxi meter, graduation design. . . 5. This product is not a precise circuit and is not suitable for use in places where high accuracy is required.
