Capacitive Touch Dimmer LED Dimmer PWM Control Switch Module

Capacitive Touch Dimmer Module is a compact and efficient LED dimmer switch that allows brightness control using capacitive touch. It works using PWM (Pulse Width Modulation) to adjust LED intensity and is suitable for embedded projects, DIY lighting systems, and smart electronics control.

Key Features:

• Capacitive Touch Control: Enables on/off and dimming via touch interface without mechanical buttons.
• PWM Output: Provides smooth and flicker-free dimming of connected LED load.
• Compact Design: Small footprint suitable for integration in tight enclosures or panels.
• Multiple Brightness Levels: Touch-based cycling between preset brightness states.
• Low Power Consumption: Efficient control without heat or mechanical wear.
