1Hz to 150KHz PWM Frequency Generator Module

Versatile signal generator module capable of producing programmable PWM outputs with frequency range from 1Hz to 150KHz and duty cycle control from 1% to 100%. Features intuitive 4-button interface for precise frequency adjustment in steps of 1Hz, 10Hz, 100Hz, or 1KHz depending on range. Clear 1.5-inch display with white text on blue backlight shows current frequency and duty cycle settings. Wide supply voltage range from 3.3V to 16V with low power consumption at 30mA no-load current. PWM output amplitude matches supply voltage with 30mA output capability. Perfect for motor control, LED dimming, servo testing, and educational electronics projects requiring precise PWM signal generation.
