Overview

Introduction

This is a PCIe to Gigabit/2.5G Ethernet adapter board designed specifically for the Raspberry Pi 5. It supports driver-free operation in Raspberry Pi OS and features a top/bottom installation design that can securely hold the Pi 5 in place

Features

• PCIe×1 Gen2 mode
• Supports only the PI5
• Ethernet port activity indicator: green LED stays on, yellow LED flashes
• Equipped with the original high-performance Realtek RTL8153 (Gigabit)/RTL8156 (2.5G) controller chip

Usage Guide

Hardware Connection

Pay attention to the orientation of the cable. Connect as shown in the diagram:

The board is powered via the PCIe interface by default, requiring no external power supply

Usage

1. Enter the config.txt file. In some cases, it might be located at sudo nano /boot/firmware/config.txt

sudo nano /boot/config.txt 

sudo nano /boot/firmware/config.txt

Enable the PCIe interface

#Add the following to the config.txt file:
dtparam=pciex1

2. The default PCIe mode is Gen2. If you need to enable PCIe Gen3, add this to /boot/firmware/config.txt:

dtparam=pciex1_gen=3
#Note that this module only supports Gen2. Setting the PI5 to Gen3 will not make a difference or increase speed for this board

3. After the modification, reboot the PI5. The device should then be recognized, as shown in the figure below (the following image is for the 2.5G version):

4. Execute ifconfig to confirm that the network card has been recognized

5. Use the ping command to test

ping baidu.com -I eth1
# -I specifies the network interface
