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 Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi 3B+/4B.
- Support PoE power over Ethernet, support IEEE 802.3af/at PoE/PoE+ network standard.
- Using a fully isolated switch mode power supply (SMPS).
- Onboard USB Type A interface, while satisfying the stable power supply of the Raspberry Pi, can also supply power to additional external devices. (5V USB-A Provides Up To 4A Output;MAX 25W For 12V+5V Total Output Power)
- Onboard high-speed active cooling fan for better heat dissipation.（Fan switchEN for auto running on powerup, DIS for disabling the fan）
- Onboard MP8676 Buck Chip:Incorporates Original Voltage Buck Chip Providing Up To 4.5A Output For Raspberry Pi And USB-A Port
- 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

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.
