Signal Generator Module Adjustable PWM Pulse Frequency Duty Cycle Square Waves Signal Generator

Features:
LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle.
Wide frequency ranges, high precision.
Used as a square waves signal generator, generate square waves signal for experimental development and use.
Used to generate a square waves signal that controls the motor driver.
Generates adjustable pulse for MCU use.
Generates adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
Serial control (single-chip TTL level communication).
