M5Stack Fader Unit with B10K Potentiometer
Description
Unit Fader is a slider potentiometer and fader unit integrated with indicator lights. It is designed with a 35mm travel slider potentiometer and 14 SK6812 programmable RGB LEDs, providing smooth analog input and customizable lighting feedback for interactive control applications.
The fader features center positioning and comfortable sliding damping for smoother, more stable, and precise control. The integrated LEDs support digital addressing, allowing each LED's color and brightness to be controlled individually. It is suitable for human-computer interaction, lighting control, music control, adjustment switches, and potentiometer level signal input.
Features
- 35mm fader travel: provides smooth slider movement for precise analog control.
- Center positioning: supports centered physical positioning for intuitive control feedback.
- Comfortable sliding damping: improves control feel and stability during adjustment.
- 10kΩ adjustable resistor: uses a single 10kΩ potentiometer for level signal input.
- Programmable RGB lights: integrates 14 SK6812 programmable RGB LEDs.
- GROVE interface: easy connection with compatible M5Stack controllers.
- Development platform support: supports Arduino and UIFlow.
