20PCS NE555 pulse frequency duty cycle adjustable module square wave rectangular wave signal generator stepper motor drive

If you need more details,please contact us.The same time asThe same time asThe same time as. / S / ygrDwnLEn7First, the scope of the module:1. As a square wave signal generator, generate square wave signal for experimental development and use.2. Used to generate a square wave signal that drives the stepper motor driver.3. Generate adjustable pulse for MCU use.4. generate adjustable pulse, control the relevant circuit.Second, a brief description:1, size: 3.1CM * 2.2CM1, the main chip: NE5552, the input voltage: 5V-15VDC. 5V power supply, the output current can be about 15MA 12V power supply, the output current can be about 35MA3, the input current: ≥ 100MA4, the output amplitude: 4.2V V-PP to 11.4V V-PP. (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%)Three advantages:1, the output with LED instructions, there is no direct output (low level LED, high LED off, the frequency is relatively low when the LED flashing)2, the output frequency range grade optional, so that the output frequency more continuous adjustableLow frequency file: 1Hz ~ 50HzIF file: 50Hz ~ 1kHzIn the high frequency file: 1KHz ~ 10kHzHigh frequency range: 10kHz ~ 200kHz3, the output duty cycle can be fine-tuned, duty cycle and frequency are not separately adjustable, adjust the duty cycle will change the frequency4, the output frequency is adjustablePeriod T = 0.7 (RA + 2RB) CRA, RB adjustable from 0-10KLow frequency file when C = 0.001UFIF time when C = 0.1UFMedium frequency file C = 1UFHigh frequency file when C = 100UF, so the frequency of the waveform buyers can calculate their own
