== '''II. Extended peripherals''' ==

=== 2.1. NVMe to WiFi6 adapter board ===
This adapter board converts the PCIe M.2 M-Key interface for hard drives on the R5S/R6C into an M.2 A-Key WiFi interface. In terms of hardware, it can be used to connect WiFi6 modules such as the MT7922, MT7921K, AX210, and AX200. It also supports WiFi5 modules like the Intel 8265C, and it can even connect to Google's Coral TPU module, the R5S can recognize the TPU device.

The hardware requires corresponding drivers in the OS to function. The latest OS for Nano Pi supports the MT7922 and MT7921.

The adapter board is 2.9mm thick and can be fully embedded inside the R5S device without the need to replace the base.

The adapter board reserves the USB Bluetooth interface for the WiFi module, with a 1.25mm-4P connector. To use Bluetooth, this interface needs to be connected to the USB port of the R5S, and Bluetooth drivers and applications are required. If Bluetooth is used, its thickness of 4.2mm makes it incompatible with the original R5S dock. You can choose to equip a 3D mounting bracket to raise the dock or replace the dock altogether.

=== 3.1 The operation of the 4G module ===

==== 3.1.1 Identify the 4G module ====
The 4G module is used as the WAN port in the FriendlyWrt. Connect the LAN port of the R5S/R5C/R6S/R6C to the PC's Ethernet port using a network cable. Power on the OS, then open the browser on the PC and navigate to 192.168.2.1 to access the FriendlyWrt's backend page (default username: <code>root</code>, password: <code>password</code>).

Click on "Services - Terminal," then log in to the terminal:

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_69.jpg

The default username is <code>root</code>, and the password is the "<code>password</code>":

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_70.jpg

Execute <code>ip addr</code>, and the result is as follows, usb0 is the Qualcomm 4G (or Qualcomm 4G-GPS, or NL668-EU/EAU/AM 4G):

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_71.jpg

If it is a CAT4 4G/ZTE CAT4/ZTE CAT4-EU module, it will be recognized as eth3 or eth2 (depending on the number of wired network ports on the device), as shown in the figure below:

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_72.jpg

'''''Note 1: The numbering of eth interfaces is based on the number of the device's own network ports, starting from 0. For example, the R5S has 3 network ports, so its own ports are numbered eth0, eth1, and eth2, and the 4G interface will be eth3. For the R5C/R6C, which have 2 network ports, the device's own ports are eth0 and eth1, and the 4G interface will be recognized as eth2.'''''

'''''Note 2: Modules such as the CAT4 4G must be inserted into the USB port only after the FriendlyWrt system has fully booted. Otherwise, the computer will not be able to obtain the correct IP address, making it impossible to access the FriendlyWrt backend configuration page.'''''

'''''Note 3: If you are using third-party firmware and the <code>eth</code> or <code>usb0</code> device does not appear in the terminal, it means the firmware was not compiled with the 4G driver, and thus 4G cannot be used. In this case, you will need to replace the firmware.'''''

Click on "Services - Terminal," then log in to the terminal.

Taking the Qualcomm 4G module as an example, execute the command <code>lsusb</code> in the terminal, as shown in the figure below:

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_86.jpg

Record the ID value of the 4G module: 05c6 90b6.

Use the following command to open the ttyUSB serial port, where the value after echo is the ID recorded above:

<code>modprobe option</code>

<code>sh -c 'echo 05c6 90b6 > /sys/bus/usb-serial/drivers/option1/new_id'</code>

After execution is complete, execute:

<code>ls /dev/ttyUSB*</code>

Now you should be able to see three devices under the dev directory: ttyUSB0 through ttyUSB2:

http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_87.jpg

Open the AT command serial port through minicom:

<code>minicom -D /dev/ttyUSB0</code>

(Note: The selection of which serial port to use should be based on entering the port and being able to input AT commands without garbled characters or erratic results.)

The first time you enter an AT command, there may be no echo. If you then type <code>at</code> and press Enter, and it returns "OK," it means the system is working properly. If you need to check the echo, type the command: <code>ATE1</code>, then press Enter. Continue typing other commands and press Enter to see the echo.

'''''Note: Network speed tests are affected by the network environment and testing methods. Please refer to the actual speed, as this test is for reference only.'''''

=== 3.3 The operation of dual WiFi ===
In the previous section, we used a single WiFi as a wireless AP. We can also insert two wireless network cards, one as a wireless AP (LAN) and the other to connect to the upstream wireless router (WAN). This way, devices like mobile phones can connect to the wireless AP and access the internet through the upstream's network via another network card.

In the previous section, we have already set one network card as a wireless AP. Now, when inserting another wireless network card and navigating to "'''Network - Wireless'''", the display is as follows:

The red box indicates the newly added second wireless network card.

Click the "Scan" button in the red box on the interface to scan the network:

After a successful connection, you can view the IP address in "Network - Interfaces":

<html><img src="http://www.mcuzone.com/wiki/4004_FriendlyElec_NanoPi_R5S/4004_FriendlyElec_NanoPi_R5S_139.jpg" width=640 style="border: 1px solid black;"></html>

We use devices such as mobile phones to connect to the hotspot set up in the previous section. Once connected, we can access the internet via the wireless hotspot, utilizing the network from the upstream router connected to the other wireless network card.

In "Network - Wireless," you can view information about the mobile phone connecting to the wireless hotspot and the wireless network card connecting to the upstream router:
