The Raspberry Pi cooling fan is a dedicated cooling solution designed for the Raspberry Pi. The Raspberry Pi is a powerful little computer, but it can generate some heat when running under heavy load. The cooling fan is designed to provide effective cooling performance and keep the Raspberry Pi running within a reasonable temperature range. It consists of PWM output chip PCA9685, 6 three-color RGB LEDs WS2812, DC power conversion circuit TPS54331, fan speed indicator LED and other circuits, and can be perfectly connected with the Raspberry Pi 40PIN GPIO header.
Product Features
- The module has strong heat dissipation performance, and the fan can generate forced convection, which can effectively reduce the working temperature of the Raspberry Pi and prevent overheating by exhausting hot air and blowing fresh air.
- The module operates with low noise, and the cooling fan adopts high-quality hydraulic bearing design to ensure silent operation
- The module is easy to install, and the cooling fan is designed based on the Raspberry Pi 40PIN GPIO header, which is easy to use and can be directly inserted into the 40PIN GPIO header of the Raspberry Pi without an additional power cord.
- Raspberry Pi cooling fans are usually compatible with various models of Raspberry Pi, such as Raspberry Pi 4B, 3B+, 3B, Zero, etc.
- There are 6 three-color RGB LEDs WS2812 on board, and the drive pin can be selected. This RGB LEDs can be used for various atmosphere displays, such as CPU temperature color display.
- There are 4 green LEDs on board, which can be used to indicate the fan speed, and the user can also freely program and define its status.
- The onboard power conversion circuit supports a wide range of DC voltage power supply from 7 to 28V, and can supply power to the Raspberry Pi motherboard at the same time.
- The on-board fan and the three-color RGB LEDs can be controlled independently by switch.
- The module additionally leads to 11 channels of PWM of PCA9685.
