52Pi PoE HAT for RPi 3B+/4B/5



PoE Hat for Raspberry Pi 3B+, 4B, and Raspberry Pi 5 The PoE Hat is a versatile accessory designed to enhance the functionality of Raspberry Pi 3B+, 4B, and Raspberry Pi 5 by providing power over Ethernet (PoE) capabilities. This allows for a more convenient setup where the Raspberry Pi can be powered directly through the Ethernet port using a PoE switch or PoE power supply. The hat is equipped with a 5.1V/4.5A output, ensuring sufficient power for the Raspberry Pi and any additional peripherals.
NOTE: Do not connect power supply to USB-C port on Raspberry Pi when you are using PoE hat, it may damage your device !!!


  • Compatibility: Designed to fit Raspberry Pi 3B+, 4B, and Raspberry Pi 5 models, offering a high level of compatibility with a wide range of Raspberry Pi boards that support PoE.
  • Power Supply: The PoE Hat supports a 5.1V/4.5A output, which is capable of delivering 25W of power. For full power operation, it requires a switch that supports the 802.3at protocol and can provide at least 30W of power.
  • Heat Dissipation: The PoE Hat has been designed with efficiency in mind, resulting in lower temperatures compared to other PoE modules. The thermal imaging shows a temperature difference of nearly 30 degrees Celsius under the same load conditions.
  • GPIO Extension: The kit includes 2x20Pin PC104 female headers to extend the GPIO pins, allowing for additional peripherals and sensors to be connected to the Raspberry Pi.
  • PoE Power Supply: It also provides 2x2Pin PC104 female headers specifically for powering the PoE interface, ensuring a stable power supply for the PoE Hat and the Raspberry Pi.
  • Adjustable Design: The PoE Hat features an adjustable design that supports different Raspberry Pi models, making it a flexible choice for various projects and setups.

This PoE Hat is an excellent addition for anyone looking to simplify the power management of their Raspberry Pi projects and take advantage of the benefits of PoE technology.
