DEVMO 2PCS NE555 Pulse Module Frequency Duty Cycle Adjustable Square Signal Generator
★As a square wave signal generator for experimental development
★Used to drive a stepper motor for generating a square wave drive signal
★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.
★nput voltage to the module (VCC) is variable from 5V to 15V DC and draws approximately 15mA at 5v (35mA at 12v) with an output amplitude of 4.2V peak-to-peak to 11.4V peak-to-peak based on the supply voltage.
