Description

The USB Knob is a versatile device that combines the functionality of a rotary encoder with the convenience of a USB interface. It is based on either the CH552E or CH554E microcontroller and is equipped with addressable LEDs, commonly known as NeoPixels. The unique combination of these components makes the USB Knob an ideal choice for a wide range of applications, including volume control for PCs.
