Description : This Auction is for Brand New 5PCS NEW NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator Stepping motor drive Free Shipping Please Visit my eBay Store for more great item: HKJE Led Lamp Center The scope of application module: 1 as a square wave signal generator generates Fang Bo signals for experimental development use. 2 square wave signal is used to drive the stepper motor driver. 3 generate adjustable pulse for MCU use. 4 adjustable pulse control related circuit. A brief description: 1, size: 3.1CM*2.2CM 1, the main chip: NE555; 2, input voltage: 5V-15VDC. 5V power supply, the output current can be around 15MA; 12V power supply, the output current can be around 35MA; 3, input current: 100MA 4, 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%) Advantage characteristic: 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 ~ 50Hz If file: 50Hz ~ 1kHz Middle and high frequency file: 1KHz ~ 10kHz High 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 FEATURES: New ! Hi Quality In excellent condition I.C.
