PoE HAT (C): Difference between revisions

Latest revision as of 12:23, 24 July 2026

Overview

The PoE HAT (C) is a Power over Ethernet (PoE+) expansion board designed specifically for Raspberry Pi 3B+ and 4B . When used with 802.3af/at compliant power sourcing equipment (such as PoE switches or routers), it delivers both network connectivity and power supply through a single Ethernet cable, eliminating the need for an additional power adapter and simplifying cabling for IoT, cluster, and industrial deployments.

Features

Based on standard Raspberry Pi 40-pin GPIO interface, compatible with Raspberry Pi 3B+/4B; stackable pass-through design supports mounting additional HATs
Supports PoE power over Ethernet, compliant with IEEE 802.3af/at PoE/PoE+ network standards
Adopts fully isolated switch mode power supply (SMPS)
Onboard original MP8676 buck chip, providing up to 4.5A total output for Raspberry Pi mainboard and USB-A port
Onboard USB Type-A interface: ensures stable power supply for Raspberry Pi while supplying power for additional external devices, with 5V 4A maximum output (power only, no data transmission)
Onboard 2-pin 12V header with 12V 2A maximum output (2.54mm Dupont)
Equipped with high-speed active cooling fan for better heat dissipation (Fan switch: EN for auto running on powerup, DIS for disabling the fan)
Please note: 25W maximum combined output power for 12V pin header and 5V USB-A port

Technical Specification

FAQ

Q1:Can USB devices be connected to the USB interface on the POE HAT?

A: No, the USB interface on the POE HAT can only output power and has no USB function.

Q2: What is the part number of the matching connector for the 12V plug on the PoE HAT C? Do you sell a cable suitable for connecting to a nearby product?

A: It's 2.54mm Dupont wire.

 ==Overview==
-The '''X15-POE1''' is a dedicated Power over Ethernet (PoE) add-on board (HAT) designed for the Raspberry Pi Compute Module 5 (CM5) when used with the '''[[X1500]]''' or '''[[X1501]] '''IO Boards. Compliant with the IEEE 802.3af/at PoE standards, this HAT can receive up to 25W of power from a compatible PoE network switch. It delivers both reliable operating power and network connectivity to the CM5 through a single Cat5e/Cat6 cable.
-Featuring an advanced dual-output design, the board supplies 5V power to the CM5 while providing an independent 12V output. This output can drive peripherals such as fans, displays, or motors. This eliminates the need for an additional external power supply, simplifying system integration and reducing clutter.
