Sscope of this module:
1. As square wave signal generator which generates a square wave signal for use experimental development.
2. used to generate drive a stepper motor drive square wave signal.
3. Adjustable pulse generation MCU for use.
4. Have an adjustable pulse control-related circuits.
1, Size: 3.1CM * 2.2CM
1, the main chip: NE555;
2, the input voltage: 5V-15VDC. 5V supply output current is about 15MA; when 12V power supply, output current is about 35MA;
3, the input current: 100MA
4, the output amplitude: 4.2V V-PP to 11.4V V-PP.?According to different input voltage, the output amplitude will be different?
5, the maximum output current: 15MA?5V power supply, V-PP is greater than 50%?, 35MA?When the 12V power supply, V-PP is greater than 50%?
1, the output with LED indication, there is no straightforward output?When the amount of low-level LED, LED blinking LED off high frequency is relatively low?;
2, the output frequency range of grades available, the output frequency is more continuously adjustable;
Low- file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High frequency gear: 1KHz ~ 10kHz
High Frequency file: 10kHz ~ 200kHz
3, they can fine-tune the output duty cycle, 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 + 2RB) C
RA, RB is adjustable 0-10K;
At low frequencies file C = 0.001UF;
IF stall when C = 0.1UF;
High frequency gear C = 1UF;
High frequency gear C = 100UF, so the frequency waveform buyers can own calculations.
