General use module generates pulses from approximately 4Hz to 1.3Khz. Utilizes the popular NE555 timer IC operating as an astable multivibrator. Module has ten-turn frequency adjustment control and power on LED. Use for stepper motor pulses, testers etc.
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.
This module is use as a square-wave signal generator. It generates square wave signals used for experimental development. It also generates square wave signal driving motor drive. With adjustable pulses generated for use by the MCU and adjustable pulse control related circuits.
