A brief description: -Size: 3.5CM * 3.6CM -The main chip: NE555; -Input voltage: 5V-15VDC. 5V power supply, the output current can about 15MA;  12V power supply, the output current can be so 35MA; -Input Current: ? 100MA -Output amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the  output amplitude is not the same) -Maximum output current:? 15MA (5V power supply, V-PP greater than 50%), ? 35MA  (12V power supply, V-PP greater than 50%) Advantages: -Output with LED indication, there is no output LED quantity (low  straightforward, high level LED off relatively low frequency LED flashes); -Output frequency range grade optional continuously adjustable output frequency; -Low-frequency stall: 1Hz ~ 50Hz -IF stall: 50Hz ~ 1kHz -In the high-frequency stall: 1KHz ~ 10kHz -High-frequency stall: 10kHz ~ 200kHz -the output duty cycle can fine-tune the duty cycle and frequency is not  adjustable separately adjust the duty cycle will change the frequency -the output frequency is adjustable; -Cycle T = 0.7*(Ra + 2*Rb)*C -Ra, Rb:0-10K adjustable; -LF gear C = 0.001UF; -IF file C = 0.1UF; -In the high-frequency file C = 1UF;, -High-frequency gear C = 100UF, the waveform frequency buyers can own  calculations. NOTE:Output duty cycle can fine-tune the duty cycle and  frequency is not adjustable separately adjust the duty cycle will change the  frequency 1x NE555 Duty Cycle and Frequency  Adjustable Module Square Wave.The main chip: NE555;. 1x NE555 Duty Cycle and Frequency Adjustable Module Square Wave. -Low-frequency stall: 1Hz ~ 50Hz. -IF stall: 50Hz ~ 1kHz. -In the high-frequency stall: 1KHz ~ 10kHz. -High-frequency stall: 10kHz ~ 200kHz.\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43037067411624,"sku":"U2I-1-311352730952","price":1290.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/s-l2000__57068_32b24e9e-f5af-4089-acaf-fdd90d63e299.jpg?v=1672673432","url":"https:\/\/shop2india.com\/products\/ne555-duty-cycle-and-frequency-adjustable-square-wave-module-new-diy-kit","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
