NE555 Pulse Frequency Generator Adjustable Duty Cycle Signal Generator Board Module

Feature: 1. Output with LED indication,when the LED is low, the LED is off, and when the frequency is low, the LED is blinking,more clear and convenient. 2. Output frequency range grade is optional,use the shorting cap to select) to make the output frequency more continuously adjustable. 3. Generate square wave signal, adjustable pulse. 4. Compact and practical design makes it works more stable. 5. Widely applicable to multiple occasions,suitable for many equipments. Specification: Item Type:Pulse Frequency Generator Size:2.9 x 3.6cm 1.14 x 1.42in Fixing Hole Distance:22.5 x 30.5mm 0.89 x 1.2in Main Chip:NE555 Input Voltage:5V 15VDC.When 5V is supplied, the output current can be around 15mA; when 12V is supplied, the output current can be around 35mA. Weight:Weight: 10 g 0.35 oz(approx.) Input Current:>=100mA Output Amplitude:4.2V V PP to 11.4V V PP. (The output amplitude will be different depending on the input voltage) Output current: more than 15mA (5V power supply, V PP is greater than 50percent ), more than 35mA (12V power supply, V PP is greater than 50percent ) Output Frequency: Low Frequency: 1Hz 50Hz Intermediate Frequency: 50Hz 1kHz Medium And High Frequency: 1KHz 10kHz High Frequency: 10 KHz 200 KHz Period T = 0.7 (RA + 2RB) C RA and RB are adjustable from 0 to 10K; C=0.001UF in low frequency gear; C=0.1UF in the intermediate frequency file; Medium and high frequency file C=1UF; C=100UF in high frequency, so the frequency of the waveform can be calculated by yourself.
