xicoolee PWM Controlled Fan HAT for Raspberry Pi Zero Zero W Zero WH 2B 3B 3B+ 4B 40PIN GPIO I2C Control Onboard PCA9685 PWM Driver

Produktbeschreibung

The cooler module for Raspberry Pi is designed based on 40PIN GPIO header for Raspberry Pi, which is easy to use and can be directly inserted into the 40PIN GPIO header intended for Raspberry Pi without an additional power cord. The cooling fan is usually compatible with various models for Raspberry Pi, such as for Raspberry Pi 4B, 3B+, 3B, Zero, etc. This heatsink module for Raspberry Pi is onboard 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 also 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 intended for Raspberry Pi motherboard at the same time. The module additionally leads to 11 channels of PWM of PCA9685.e on-board fan and the three-color RGB LEDs can be controlled independently by switch The onboard power conversion circuit supports a wide range of DC voltage power supply from 7 to 28V, and can supply power to intended for Raspberry Pi motherboard at the same time. The module additionally leads to 11 channels of PWM of PCA9685 The cooling fan expansion for Raspberry Pi has strong heat dissipation performance, and the fan can generate forced convection, which can effectively reduce the working temperature of RPI series boards and prevent overheating by exhausting hot air and blowing fresh air
