for Raspberry Pi 4B /3B + /3B /3A + Cooling Fan with LED Light, GPIO Function Expansion, and Effective Heat Dissipation - Yunseity, Yunseity3z1fnecsao

• Compatible for for Raspberry Pi pins of 40P, direct plug to use, side winds out, and the upper expansion heat dissipation is not affected. Clear identification of pins, enable GPIO functions at a , GPIO is completely expandable, and the heat dissipation does not affect the development or use. There is on/off to control the cooling fan and LED light, It is recommended to always open when using for for . Specially 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. Well ventilated, heat can be discharged in time, all GPIOs are led out without taking up space, keeping for for Raspberry Pi connection convenient.
