5V Square USB Fan - 5 cm

• USB-Powered Convenience - Just plug into any USB port for rapid cooling.
• Direct 5V Power Option - Remove the USB connector and wire directly to a 5V power source.
• PWM Control Ready - Without a dedicated PWM/feedback pin, you can use a motor controller, H-Bridge, or MOSFET for basic speed control. Remember to add a flyback diode to protect your circuit from inductive loads. The MOSFET Driver Stemma is a great choice for easy setup.
• Multiple Sizes Available - Select the perfect fan size for your project.

Using this 5V square USB cooling fan is super easy. You can simply plug it into any USB port for quick cooling. If you prefer, you can cut off the USB connector and wire it directly to a 5V power source. When using it for speed control, without a dedicated PWM/feedback pin, you can use a motor controller, H - Bridge, or MOSFET. But don't forget to add a flyback diode to protect your circuit. The MOSFET Driver Stemma makes the setup a breeze. Each fan comes with front and back grills, and mounting screws and nuts for a secure installation. For maintenance, keep it clean from dust regularly. And when using the direct 5V power option, make sure the wiring is correct to avoid any short - circuits.
