Adafruit NeoSlider I2C QT Slide Potentiometer with 4 NeoPixels

Add a smooth slide control to any I2C project with the Adafruit NeoSlider — a 75 mm linear slide potentiometer with four RGB NeoPixel underlights, all communicating over I2C via the onboard seesaw microcontroller. No analog pins needed on your main board.

Thanks to the STEMMA QT / Qwiic connectors on the underside, wiring is solderless — just plug in a compatible cable and start reading the slider position and controlling the NeoPixels over I2C. Chain up to 16 NeoSliders on a single I2C bus by cutting the address selection jumpers (default address 0x30, configurable up to 0x3F).

Key Features

• 75 mm Linear Slide Potentiometer – Smooth-action slider with analog readout via I2C
• 4 RGB NeoPixels – Underlighting LEDs for visual feedback, individually controllable
• I2C Seesaw Interface – Onboard microcontroller handles analog reads and NeoPixel control
• STEMMA QT / Qwiic Connectors – Solderless I2C connection on both sides for daisy-chaining
• Chainable – Up to 16 boards on one I2C bus via address jumpers (0x30–0x3F)
• 3 V and 5 V Compatible – Works with both 3.3 V and 5 V logic levels
