Digital 2 Channel PWM Square Wave Pulse Signal Generator Adjustable Frequency Duty Cycle 100% 1Hz - 150KHz Module

This 2-channel PWM pulse / square wave generator provides two pulse / square wave outputs with independent control over each channel's duty cycle and frequency using the LED display and set/up/down buttons. It can also be programmed through its serial RS-232 interface.

Applications include:

• A square wave generator to generate square wave signals for experimentation and control
  
• Driving stepper motors
• Generating adjustable pulses for microcontroller use
• Generating adjustable pulses for PWM control of lighting and LEDs
