Unit Fader is a slider potentiometer/fader integrated with indicator lights, designed with a 35mm travel slider potentiometer and 14x SK6812 programmable RGB lights. The fader features center positioning, and its excellent sliding damping provides smoother, more stable, and precise control. The integrated LEDs support digital addressing, meaning you can individually control the color and brightness of each LED to achieve various lighting effects. This product is suitable for applications… (M5Stack U123)
