5 pcs NE555 Pulse Frequency Duty Cycle Square Wave Signal Generator Stepper Motor Driver

【Technical Specifications】The square wave signal generator operates with an input voltage ranging from 5V to 15VDC and requires an input current of no less than 100mA. It can deliver a maximum output current of no less than 15mA, with an output current of approximately 15mA at 5V input and around 35mA at 12V input.
【Indicator Feature】The NE555-based pulse frequency module, adjustable in duty cycle, is equipped with a red LED indicator. This indicator shows the clarity of the output signal (the LED is active at a low level, inactive at a high level, and flashes at low frequency).
【Versatile Applications】 This versatile square wave signal generator is capable of producing adjustable pulses for a variety of applications, including controlling associated circuits, providing pulses for Microcontroller Unit (MCU) use, driving stepper motor drivers, and generating signals for experimental and developmental purposes.
【Operational Caution】When adjusting the frequency using a jumper cap, it is important to disconnect the power supply before making the change. Once the jumper cap is in place, the power can be safely reapplied.
【Quality Assurance】Our products are manufactured under stringent quality control measures, ensuring stable performance and dependable quality. You can trust and use our products with confidence over an extended period.
