1. Is used as a square wave signal generator generates a square wave signal used for experimental development.
2. To drive a stepper motor for generating a square wave drive signal.
3. Adjustable pulse generated for use by MCU.
4. Adjustable pulse generation, control circuitry associated.

1. The main chip: NE555;
2. Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around;
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%).

1. The output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes);
2. The output level selectable frequency range, the output frequency is more continuously adjustable;  - LF file: 1Hz ~ 50Hz  - IF file: 50Hz ~ 1kHz  - High-frequency file: 1KHz ~ 10kHz  - HF file: 10kHz ~ 200kHz
3. The output duty cycle can fine-tune, duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency;
4. The output frequency is adjustable;  - Period T = 0.7 (RA +2 RB) C  - RA, RB is 0-10K adjustable;  - Low profile when C = 0.001UF;  - IF stalls C = 0.1UF;  - High-frequency file C = 1UF;  - HF stalls C = 100UF, so the frequency of the waveform buyers can own calculations.
