USB Fan Speed Controller Compact Design Rotary Knob Fan Regulator USB Rotary Controller Printed Dimensions

This compact electronic accessory is a USB fan speed controller module built on a small blue printed circuit board with a black rotary knob and blue top, combining a simple layout with integrated USB jacks. As a fan controller, it uses one USB male plug and one USB female socket to sit between power and the device, while the rotary knob serves as both the control and switch. This USB fan speed controller uses a rotary adjustment style that keeps operation straightforward, letting you manage output with a single turning action on the knob. The USB rotary controller is designed with integrated plug-and-socket construction, making the module easy to place in a USB-powered setup without extra components. As a USB switch module, its small rectangular board shape and printed dimensions of 50.4 mm, 35.1 mm, and 17.4 mm support a neat, slim installation where space is limited.
