The Raspberry Pi cooling fan serves as a specialized cooling solution tailored for the Raspberry Pi. While the Raspberry Pi boasts impressive computing power for its size, it may encounter heat buildup during intensive tasks. To address this, the cooling fan is engineered to deliver efficient cooling performance, ensuring the Raspberry Pi remains within a safe operating temperature range.
Comprising a microcontroller STM32F030F4P6, 6 tri-color RGB LEDs (WS2812), a DC power conversion circuit (TPS54331), a fan speed indicator LED, a fan mode switch, and other essential circuits, this cooling fan seamlessly integrates with the Raspberry Pi's 40-pin expansion connector.
Product Features
- The module has an onboard independent control chip, allowing manual adjustment of the fan speed without the need to run control code on the Raspberry Pi.
- The module offers powerful cooling performance, as the fan can create forced convection by expelling hot air and delivering fresh air, effectively reducing the operating temperature of the Raspberry Pi and preventing overheating.
- The module operates with low noise; the cooling fan utilizes a high-quality hydraulic bearing design to ensure quiet operation.
- Easy installation: The cooling fan is designed based on the Raspberry Pi's 40-pin expansion interface, making it simple and convenient to use. It can be directly plugged into the Raspberry Pi's 40-pin expansion interface without the need for additional power cables.
- Onboard 6 full-color RGB LEDs (WS2812), which can be used for various ambient displays, such as displaying CPU temperature in different colors.
- Onboard 4 green LEDs, which can be used for fan speed indication. Users can also freely program and define their states.
- Onboard power conversion circuit, supporting a wide range of DC voltage input from 7 to 28V, can simultaneously power the Raspberry Pi mainboard.
- Independent control switches for the onboard fan and full-color RGB LEDs.
