This round scrubber knob is designed to pair with a rotary encoder, giving you a broad, easy-to-grip control surface for fast spinning and one-finger adjustments.
The face includes a finger groove, making it handy for menu navigation, jog wheels, scrub controls, and other encoder-based interfaces where continuous rotation is useful.
It snaps onto a compatible rotary encoder and does not include the encoder itself. Please note that this knob is not suitable for Adafruit potentiometers with T18 spline shafts, even though potentiometers and rotary encoders can look similar.
Specifications:
- Diameter: 34.7mm / ~1.3"
- Height: 10.5mm / 0.4"
- Weight: 2.1g
Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
