PCIe TO 2.5G ETH Board (C)
| ||
Overview
Introduction
This is a PCIe to 2.5G Ethernet adapter board designed specifically for the Raspberry Pi 5, featuring driverless support for Raspberry Pi OS
Features
- PCIe ×1 Gen2 mode
- Only supports PI5
- Ethernet port status indicators: the green LED flashes during data transmission, and the yellow LED stays on when a connection is established
- Equipped with the original high-performance Realtek RTL8125 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. Enable the PCIe interface
Add the following line to /boot/firmware/config.txt: 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, and the device can be recognized.
As shown below, you can use the lspci command to identify our RTL8125 device
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 specifes the network interface
Other Systems
If you are not using Raspberry Pi OS but another system supported by the Raspberry Pi, you may encounter an issue where the PCIe device is detected but the corresponding network card will not appear
The kernel needs to be recompiled
