LORDWORLD Power Over Ethernet HAT (E) development board

SKU CH-TS5V-BNQRZ

Powers a Raspberry Pi 3B+ or 4B through an Ethernet cable using an IEEE 802.3af-compliant isolated supply that fits inside the official case

  • Powers Raspberry Pi 3B+ and 4B through Ethernet cable
  • IEEE 802.3af-compliant PoE for reliable network delivery
  • Fully isolated SMPS protects board from power faults
  • Compact layout fits inside official Raspberry Pi case
  • Single cable carries both data and power

Compatible Raspberry Pi Models

This PoE HAT fits the Raspberry Pi 3B+ and 4B boards. It is designed to sit inside the official Raspberry Pi case without modification. Makers and embedded developers can add wired power and data through a single Ethernet cable.

Power Delivery and Headroom

The on-board isolated SMPS converts PoE input to the 5 V rail required by the Pi. It handles the standard 802.3af power budget, which is sufficient for typical headless or lightly loaded applications. Heavy peripheral draw or sustained CPU loads may exceed the available headroom.

IEEE 802.3af Practical Limits

The HAT follows the IEEE 802.3af specification, so it negotiates up to the standard power class with compatible switches or injectors. Long cable runs, non-compliant injectors or switches with limited PoE budgets can reduce the power actually delivered to the board.

Perguntas sobre este artigo

Will the HAT fit inside the official Raspberry Pi case when mounted on a Pi 3B+?

The compact component layout is designed to be compatible with the official Raspberry Pi case on both the 3B+ and 4B models.

How can I verify the board is delivering power correctly after installation?

The Pi should boot and operate normally using only the Ethernet cable connected to an IEEE 802.3af-compliant PoE switch or injector.

Does the package include a Raspberry Pi board or a PoE injector?

The product is the HAT development board only; a compatible Raspberry Pi 3B+ or 4B and a PoE-capable network source must be supplied separately.
