5Pcs Pulse Duty Cycle Adjustable Module NE555 Squares Rectangular Wave Signal Generator

5Pcs Pulse Duty Cycle Adjustable Module NE555 Squares Rectangular Wave Signal Generator Description

1¡Indicator Light: The output has LED indication, and clear whether there is output (the amount of LED when the level is low, the LED is off when the level is high, and the LED flashes when the frequency is relatively low) 2¡Ideal Wave: There are 4 jumpers and 2 variable resistors on the module, users can adjust the output wave with these components to easily achieve the ideal wave 3¡Work Cycle: The output working cycle can be fine tuned, and the working cycle and frequency cannot be adjusted separately. Adjusting the working cycle will change the frequency 4¡Frequency Range: The capacitance capacity of this pulse frequency adjustment module determines the frequency range, and users can calculate and adjust according to their own needs 5¡Basic Specifications: Input voltage is 5V-15VDC, when 5V power supply, the output current can be around 15MA, when 12V power supply, the output current can be around 35MA
