Features: 1Compatible for Raspberry Pi pins of 40P, direct plug to use, side winds out, and the upper expansion heat dissipation is not affected. 2Clear identification of pins, enable GPIO functions at a glance, GPIO is completely expandable, and the heat dissipation does not affect the development or use. 3There is on/off to control the cooling fan and LED light, It is recommended to always open when using for Raspberry Pi. 4Specially increase the height between the fan and the chip, expand the negative pressure area and heat dissipation is more effective. Using hydraulic bearing fan, low operating noise and has long service life. 5Well ventilated, heat can be discharged in time, all GPIOs are led out without taking up space, keeping for Raspberry Pi connection convenient. Condition: 100% Brand New Item Type: Cooling Fan for Raspberry Pi Material: PCB Color: Black Rated Voltage: DC5V Current:
