NE555 pulse frequency adjustable duty cycle square wave module rectangular wave signal generator
PLS NOTE: THIS IS ONLY 1PCS,WE MADE MISTAKE ON IT
First, the module Scope:
1. As square wave signal generator generates a square wave signal for experimental development use.
2. used to generate drive a stepper motor drive square wave signal.
3. produce an adjustable pulse for MCU to use.
4. Have an adjustable pulse control-related circuits.
Second, a brief description:
1, Size: 2.9CM * 3.6CM, fixing hole distance 22.5 * 30.5MM
2, the main chip: NE555;
3, the input voltage: 5V-15VDC. 5V supply, the output current can be around 15MA; when 12V power supply, output current is about 35MA;
4, module weight: 10 g;
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 output current: (a 5V power supply, V-PP is greater than 50%) ≥15MA, ≥35MA (12V power supply, V-PP is greater than 50%)
Three Advantages:
1, the output with LED indication, there is no straightforward output (low level LED quantity LED off high frequency is relatively low LED flashing);
2, the output frequency range grade is optional (by shorting cap put option) the output frequency is more continuously adjustable;
Low-profile: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High-frequency gear: 1KHz ~ 10kHz
High Frequency file: 10kHz ~ 200kHz
3, it can fine-tune the output duty cycle, duty cycle and frequency are not separately adjustable, adjust the duty cycle will change the frequency; and, if desired duty cycle and frequency are adjustable module, please click on the following link to purchase:
4, the output frequency is adjustable;
Cycle T = 0.7 (RA + 2RB) C
RA, RB is adjustable 0-10K;
When the low-profile C = 0.001UF;
When IF shift C = 0.1UF;
High-frequency gear C = 1UF;
When high-frequency gear C = 100UF, therefore frequency waveform buyers can own calculations.
