The input signal voltage range of 3V–24V makes this module fully compatible with Arduino, STM32, ESP32, and other 3.3V or 5V microcontroller I\/O pins. The optocoupler ensures the control circuit is completely isolated from the load circuit, protecting your microcontroller from voltage spikes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this module support PWM signals for speed or brightness control?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The F5305S MOSFET on this board supports PWM (Pulse Width Modulation) input, allowing you to precisely control DC motor speed, LED strip brightness, pump flow rates, and more by varying the duty cycle of your PWM signal.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
