Description:

【Product Type】: This electronic accessory is a compact USB voltage module designed for DIY electronics, giving you a simple way to add adjustable power control to small USB-powered projects.

【Primary Function】: As a voltage controller, it lets you regulate output with ease, making it practical for projects that need a stable and adjustable power level rather than a fixed USB supply.

【Speed Control】: Built as a fan speed controller, it works as a USB fan speed regulator for fine-tuning ventilation, so you can match cooling or comfort to the situation instead of running at single constant speed.

【Built-in Circuit】: The integrated voltage step-up and buck circuit helps support wider voltage adjustment needs, therefore USB voltage module is more flexible for different USB-powered devices and custom builds.

【Compact Design】: Measuring about 46 x 21 by 18 mm, the small body fits neatly into tight setups, making it easy to install, carry, and keep your workspace clean and uncluttered.
