PoE controllers allow the Raspberry PI to be powered through the ethernet connector. No need for a mini-USB or USB-C power supply!
To power the RPI, you need an ethernet switch that is IEEE 802.3af or IEEE 802.3at compatible.
This hat provides ethernet power to the RPI and has a monochrome oled screen and a programmable DC fan (on/off). It is possible to force the activation of the fan by a switch on the card.
This hat is RPI 3b+ and RPI 4 compatible.
The recalbox-wpaf utility supports this hat and allows to control the fan (on/off depending on the CPU temperature).
This hat allows the RPI to be powered by ethernet and has a variable speed fan (PWM).
This hat is compatible with RPI 3b+ and RPI4.
The recalbox-wpaf utility supports this hat and allows to control the fan (enable/disable depending on the CPU temperature).
This type of board has a fan to cool the CPU.
This board is attached to a part of the GPIO connector of the Raspberry PI. It has a silent fan, an RGB LED and a button. The fan function is supported by the recalbox-wpaf utility.
