UCTRONICS PoE hat for Raspberry pi
Brand: UCTRONICS
Color: Mini PoE HAT

UCTRONICS U6109 PoE HAT for Raspberry Pi is to use with the Raspberry Pi models with PoE pins like Raspberry Pi 3 Model B+ and Raspberry Pi 4 Model B, so you can power the Raspberry Pi with a single Ethernet cable plugged in.

For Pi 4 and 3 B+: This PoE HAT can be used to deliver clean and reliable power to the raspberry pi 3 model B+ and raspberry pi 4 model B (not included).
Output Power: DC 5V (2.5A Max); Total Power Budget: 12.5W; IEEE 802.3af Compliant
Smaller Size: Nearly half the official size, save more space for your other hardware, can be held in the most case for Raspberry Pi.
Well-ventilated Environment Recommended: It’s normal to become hot when the HAT operating. Please make sure the adequate air circulation to help it dissipate heat to ensure stable operation. If used with Pi 4, you can search ASIN B07WMNXB4V to get the case with the fan.
NOTE: The network switch or power sourcing equipment (PSE) is needed to supply the PoE signal, and they must be compliant with the IEEE 802.3af or 802.3at PoE standard, particularly section 33.4.1 with regards to PSE electrical isolation of the leads. For the non-isolated switch, such as some Ubiquiti switches can not provide proper isolation, they can only work with CAT 5E and CAT 6E network cable.
