NE555 Adjustable Frequency Module Square Wave Rectangular Signal Generator Article-Nr.:5400775 Product Details: Product Details: Signal Generator Module Condition: New Scope of this module: 1 Used as a square wave signal generator generates a square wave signal used for experimental development. 2 To drive a stepper motor for generating a square wave drive signal. 3 Adjustable pulse generated for MCU. 4 Adjustable pulse generation, control circuitry associated Description: 1 Size: approx.3.1CM * 2.2CM 2 Main chip: NE555; 3 Input voltage: 5V-15VDC. When 5V power supply, the output current can 15MA around; When 12V power supply, the output current can 35MA around; 4 Input current: >= 100MA 5 Output range: 4.2V V-PP to 11.4V V-PP. (Different input voltage cause different output) 6 Maximum output current: >= 15MA (when 5V power supply, V-PP greater than 50%), >= 35MA (when 12V power supply, V-PP greater than 50%) Advantages: 1 Output with LED indication, easy to see(low volume LED will light, high volume LED will off, LED flash when frequency is relatively low); 2 Output level selectable frequency range, the output frequency is continuously adjustable; LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz Medium-high frequency file: 1KHz ~ 10kHz HF file: 10kHz ~ 200kHz 3 The output duty cycle can fine-tune, duty cycle and frequency can not separately adjustable, adjusting the duty cycle will change the frequency 4 Output frequency is adjustable; Period T = 0.7 (RA +2 RB) C RA, RB is 0-10K adjustable; LF file C = 0.001UF; IF file C = 0.1UF; Medium-high frequency file C = 1UF; HF file C = 100UF, so you can count the frequency of the waveform Color: show as pictures PLS NOTE that due to lighting effects, monitor's brightness / contrast settings etc, there could be some slight differences in the color tone of the pictures and the actual item!
