5V Square USB Fan - 9 cm

• USB Plug-and-Play: Just plug it in and start using right away.
• Direct 5V Wiring: Cut the USB connector to wire directly to a 5V power source.
• There's no built-in PWM or feedback pin, but you can control the fan speed with a motor controller, H-Bridge, or MOSFET.
• As fans are inductive loads, a flyback diode is needed to protect your circuitry. We suggest using the MOSFET Driver Stemma for easy setup.

Using this 5V USB cooling fan is super easy. You can either use the USB plug-and-play feature - just plug it into a USB port and it'll start working right away. If you prefer, you can cut off the USB connector and wire it directly to a 5V power source. To control the fan speed, you can use a motor controller, H - Bridge, or MOSFET. Remember, since the fan is an inductive load, you need to use a flyback diode to protect your circuit. We recommend the MOSFET Driver Stemma for easy integration. When installing the fan, use the included front and back protective grills, mounting screws, and nuts to ensure it's securely in place. For maintenance, keep the fan clean by gently removing any dust or debris from time to time. This will help it keep working efficiently and last longer.
