1. Introduction
The Waveshare PoE HAT (G) is a Power Over Ethernet (PoE) hardware attached on top (HAT) designed for the Raspberry Pi 5. This HAT enables the Raspberry Pi 5 to receive both power and network connectivity through a single Ethernet cable, provided it is connected to an IEEE 802.3af/at-compliant PoE router or switch. It offers a stable 5V 5A output and is compatible with the official Raspberry Pi 5 case, making it suitable for various embedded applications.

5. Setup and Installation
Follow these steps to install the Waveshare PoE HAT (G) onto your Raspberry Pi 5:
- Prepare the Raspberry Pi 5: Ensure your Raspberry Pi 5 is powered off and disconnected from any power source.
- Attach the Standoffs: Secure the included brass standoffs to the mounting holes on the Raspberry Pi 5 board.
- Mount the PoE HAT (G): Carefully align the 40-pin GPIO header of the PoE HAT (G) with the corresponding pins on your Raspberry Pi 5. Gently press down until the HAT is firmly seated.
- Secure the HAT: Use the provided screws to secure the PoE HAT (G) to the standoffs, ensuring a stable connection.
- Install in Official Case (Optional): If using the official Raspberry Pi 5 case, the compact design of the PoE HAT (G) allows it to fit inside. Follow the case's instructions for assembly after the HAT is installed.
- Connect Ethernet Cable: Connect an Ethernet cable from an IEEE 802.3af/at-compliant PoE router or switch to the Ethernet port on your Raspberry Pi 5. This cable will provide both power and network connectivity.

7. Troubleshooting
- No Power/Network:
- Ensure your PoE router or switch is IEEE 802.3af/at compliant.
- Verify the Ethernet cable is securely connected at both ends.
- Check the PoE HAT (G) for proper seating on the Raspberry Pi 5's GPIO header.
- Low Power Warnings for USB Peripherals:
- The default Raspberry Pi OS may limit USB power when using PoE. To increase the power limit for USB ports (up to 1.6A), edit the
/boot/firmware/config.txtfile. - Add the line
usb_max_current_enable=1at the bottom of the file. Save and reboot your Raspberry Pi 5.
- The default Raspberry Pi OS may limit USB power when using PoE. To increase the power limit for USB ports (up to 1.6A), edit the
- Insufficient Power for High-Demand Applications:
- If your Raspberry Pi 5 and its peripherals require more than 15W, ensure your PoE router or switch can provide a 30W output (PoE+). Standard PoE switches typically provide 15W per port.
8. Maintenance
The Waveshare PoE HAT (G) requires minimal maintenance. To ensure optimal performance and longevity:
- Keep the HAT and Raspberry Pi 5 in a clean, dry environment, free from dust and moisture.
- Avoid exposing the device to extreme temperatures.
- Handle the HAT by its edges to prevent damage to electronic components.
- Periodically check connections to ensure they remain secure.
