Description This for Raspberry Pi cooling fan is a dedicated cooling solution designed for Raspberry Pi. The RPi is a powerful small computer, but under heavy loads, it may generate some heat. The cooling fan is designed to provide effective cooling performance and keep the RPi operating within a reasonable temperature range. It consists of a microcontroller STM32F030F4P6, 6 tri-color RGB LEDs (WS2812), a DC power conversion circuit (TPS54331), fan speed indicator LED, fan mode switch, and other circuits. It can be perfectly connected to the RPi 40-pin expansion connector. 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 RPi. 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 RPi 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 RPi's 40-pin expansion interface, making it simple and convenient to use. It can be directly plugged into the RPi'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 RPi mainboard. Independent control switches for the onboard fan and full-color RGB LEDs. Package includes 1. SG-FAN-HAT-B*1 2. Copper post Screws pack *1 3. Heatsink Kit *1
