I. Introduction

The Raspberry Pi 5 features a 16-pin PCIe interface, through which various PCIe devices can be connected. This expansion board is specifically designed for the Raspberry Pi 5 to serve as a WiFi 7 adapter. This module requires driver installation to use WiFi 7 on the Raspberry Pi system, while it is plug-and-play under Ubuntu without needing additional drivers. The module also supports WiFi 6 and WiFi 5 via the M.2 E key interface.

II. Hardware Spec

1. PCIe expansion board designed specifically for the Raspberry Pi 5;

2. One M.2 E-Key PCIe interface, supporting the BE200 WiFi 7 module, with hardware also supporting WiFi 6(E) and WiFi 5, such as AX210, AX200, MT7922, and Intel 8265C;

3. One USB Bluetooth interface (built-in with the WiFi module), exposed via a 1.25mm 4-pin USB connector. To use the Bluetooth function, this USB must be connected to a USB 2.0 port on the Raspberry Pi 5, and it requires the appropriate drivers and profiles to be installed;

4. Reserved CSI/DSI cable routing slots, supporting 22-pin cables with 0.5mm pitch and 15-pin cables with 1mm pitch;

5. Board-mounted power indicator light ('PWR') and one WiFi activity indicator light ('ACT');

6. Uses an efficient DC-DC circuit;

7. Gold immersion PCB process, lead-free production, certified by UL, compliant with ROHS standards, and has a fire rating of 94V-0;

8. The board has four M2.5 mounting holes, with a recessed design on the top of the board to facilitate the use of the 40-Pin GPIO;

9. Optional PCB antenna or SMA antenna, with an IPEX4 interface;

10. Optional aluminum alloy enclosure.

IV. Work with Raspberry Pi OS

4.1 Installing WiFi 7 driver (BE200)

Note: Once the WiFi 7 driver (BE200) is successfully installed, the original WiFi module on the Raspberry Pi 5 will no longer be usable!

This installation procedure also applies to the AX210 (WiFi 6E) and AX200 (WiFi 6) modules.

4.1.1 Update the system and header files

Execute commands in the Raspberry Pi terminal:

sudo apt-get update

sudo apt install -y raspberrypi-kernel-headers firmware-iwlwifi flex yacc

4.1.2 Download and extract the source code

Execute commands in the Raspberry Pi terminal:

mkdir wifi && cd wifi

wget http://www.mcuzone.com/wiki/0011_MPW7/backport-iwlwifi-20231029.tar.bz2

sudo tar -xvf backport-iwlwifi-20231029.tar.bz2

4.1.3 Compilation Environment

Execute commands in the Raspberry Pi terminal:

sudo make defconfig-iwlwifi-public

sudo sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config

4.1.4 Compile source code

Execute commands in the Raspberry Pi terminal:

sudo make -j 4

sudo make install

At this point, the system will prompt you to restart. Please do not restart yet.

4.1.5 Install firmware (not necessary for AX200 or AX210)

Execute commands in the Raspberry Pi terminal:

cd ..

cd Downloads

wget http://www.mcuzone.com/wiki/0011_MPW7/firmware_wifi7.zip

unzip firmware_wifi7.zip

sudo cp iwlwifi-gl-c0-fm-c0-86.ucode /lib/firmware

sudo cp iwlwifi-gl-c0-fm-c0.pnvm /lib/firmware

Then reboot system:

sudo reboot

4.2 Test of WiFi 7 module: BE200

After restarting the system, we execute lspci in the terminal:

You can see the WiFi 7 module.

Execute ifconfig -a to view the information of the wireless network card (wlan0):

At this point, you can use the BE200 (WiFi 7) module to connect to a wireless AP through the network connections settings:

In the network connection information, you can also see the network connection using the iwlwifi driver:

通过BE200（WiFi7）模块连接外网（200M宽带）测速，结果如下：

Note: Network speed tests are influenced by the network environment and testing methods. The speeds shown are for reference only and may vary based on actual conditions！

Connect to the WiFi 7 router and perform a speed test:

Note: All tests here are conducted using SSH to connect to the development board.

The router used is the Xiaomi BE6500 Pro, a WiFi 7 + quad-port 2.5G router. The Raspberry Pi 5 with WiFi 7 is approximately 1 meter away from the router.

Using the BE200 + Raspberry Pi 5, connect to the WiFi 7 wireless network and perform an iperf3 speed test with a Windows system (2.5G USB network card, IP address: 192.168.8.197) connected to the same router:

Speed test with 30 threads, results as follows

iperf3 -c 192.168.8.197 -P 30

Speed test with 30 threads, results as follows

iperf3 -c 192.168.8.197

Approximately 500 Mbps.

For comparison, we replaced the WiFi 7 module with a WiFi 6 module (AX210) and performed the same tests.

Speed test with 30 threads, results as follows:

Approximately 847 Mbps.

Single-thread speed test, results as follows:

iperf3 -c 192.168.8.197

Approximately 456Mbps。

Note: Network speed tests are influenced by the network environment and testing methods. The speeds shown are for reference only and may vary based on actual conditions！

4.3 Bluetooth Testing

Connect the 1.25mm 4-pin USB Bluetooth interface to the USB 2.0 port on the Raspberry Pi 5:

On Raspberry Pi OS, the Bluetooth module of the Raspberry Pi 5 is recognized directly. Click on the device icon in the top-right corner of the desktop, then click Add Device...:
