for Raspberry Pi 5 PoE Hat, 5V 4.5A Power Over Ethernet for Raspberry Pi 4B, 3B+, Support IEEE 802.3af or 802.3at PoE Standard with Active Cooling Fan

Note: Always install all four hex standoffs when mounting the PoE HAT to prevent metal contact and electrical arcing;
Wide Compatibility: This PoE+ hat is compatible with Raspberry Pi 5 and Pi 4B/3B+, and occupies only 6 pins of the 40-pin GPIO, which makes your Raspberry Pi be available for further use that needs to connect to the GPIO Pins;
High Power Budget: This Raspberry Pi 5 PoE HAT is IEEE 802.3 af/at compliant, max output of 5V 4.5A, input 45-57V, Class 4 PoE device.
Note: PoE power output must be within the budget of the switch when powering multiple boards; Fully isolated switch mode power supply (SMPS) for stable power delivery;
Efficient Heat Dissipation: This Raspberry Pi hat has an On-board active cooling fan and aluminum heatsink for efficient cooling;
Easy Setup: This PoE hat as development board accessories is pre-assembled and ready to use, only need M 2.5 screws for being installed on a Raspberry Pi or replace the M 2.5 Female -Female standoffs with M 2.5 Male-Female standoffs come with the parcel, if you want to use it on a rack; Uctronics
Racks Compatibility: This Uctronics PoE hat supports mounting on most of UCTRONICS rack mounts, e. g., RM0013/RM0004
