The scope of application of this module:1 used as a square wave signal generator, generating square wave signal for the experimental development and use.2 square wave signal is used to drive the stepper motor driver.3 generate adjustable pulse for MCU use.4 generate adjustable pulse, control the related circuit.Two, a brief description:1, size: 3.1CM*2.2CM1, the main chip: NE555;2, input voltage: 5V-15VDC. 5V power supply, the output current can be around 12V; 15MA power supply, the output current can be around 35MA;
3, input current: 100MA4, the output range: V-PP 11.4V to V-PP. 4.2V (according to the input voltage is different, the output will be different)5, the maximum output current: 15MA (5V power supply, V-PP is greater than 50%), or 35MA (12V power supply, V-PP is greater than 50%)
Three advantage characteristics:1, the output with LED instructions, there is no direct output (low power usually LED, high level LED out, the frequency is relatively low when the LED flashing);2, the output frequency range of grades, so that the output frequency can be adjusted more continuously;Low frequency file: 1Hz ~ 50HzIf file: 50Hz ~ 1kHzMiddle and high frequency file: 1KHz ~ 10kHzHigh frequency file: 10kHz ~ 200kHz
3, the output duty cycle can be fine tuned, duty cycle and frequency are not adjustable, adjustable duty cycle will change frequency;
4, the output frequency can be adjusted;Cycle T=0.7 (RA+2RB) C
RA, RB adjustable for 0-10K;
Low frequency C=0.001UF;If the file is C=0.1UF;Middle and high frequency file C=1UF;High frequency file C=100UF, so the frequency of the waveform can be calculated by the buyer.
