This NE555 square wave pulse generator module can be used to produce square wave signals for experimental development, or in applications such as driving stepper motors, and as an adjustable pulse for microcontroller (MCU) applications.
Only 31mm x 22mm (1.2″ x 0.9″), the board features an NE555 timer chip with jumpers and a potentiometer to fine-tune the frequency in four frequency ranges, and a second potentiometer to adjust the duty cycle (the relationship of how long the output is driven HIGH versus driven LOW). For example, a 50% duty cycle means the output is high 1/2 the time, and low 1/2 the time.
Applications:
As a square wave signal generator for experimental development
Used to drive a stepper motor for generating a square wave drive signal
Generate adjustable pulses for microcontrollers (MCU)
Package Includes:
2X (2 Pieces) NE555 Duty Cycle Adjustable Pulse Frequency Square Wave Signal Generator Module
