If you are using wired ethernet internet, please insert the network cable into the RJ45 port on the ArmSoM-W3, and then the wired connection prompt will pop up on the system desktop.

How to manually configure ethernet?

Switch to root user

sudo su

Use the command -ifconfig to check if ethernet is working properly, then showing the eth0 or enP4p65s0 network card and ethernet IP address. Also use the ping tool to test connectivity to the network.

ifconfig
ping www.baidu.com

If unable to ping, please try:

$ sudo dhclient eth0
or 
$ sudo dhclient enP4p65s0

RGB LED

The ArmSoM-W3 has a power LED and user LED.

Power Indicator LED
The power LED is green. On the ArmSoM-W3 it is solid on by default when powered.
User Indicator LED
The user LED is blue. By default its blinking state shows a running kernel.

The user can control via commands:

armsom@armsom-w3:/# sudo su
root@armsom-w3:/# echo timer > /sys/class/leds/blue:status/trigger
root@armsom-w3:/# echo activity > /sys/clas

RTC

The ArmSoM-W3 is equipped with an RTC IC hym8563.
First, insert the RTC battery to power the RTC IC.
Note that we should keep the RTC battery in the RTC connector and confirm the rtc hym8563 device has been created

armsom@armsom-w3:/#  dmesg | grep rtc
[    6.407133] rtc-hym8563 6-0051: rtc information is valid
[    6.412731] rtc-hym8563 6-0051: registered as rtc0

Locating rtc0, then use the following commands to set system time and sync to rtc0.

armsom@armsom-w3:/# hwclock -r

M.2 Interface

The ArmSoM-W3 provides two M.2 connectors:

There is an M.2 E Key connector on the front of the board with a 2230 mounting hole, providing PCIe 2.1 single-channel, USB, SATA, SDIO, PCM and UART signals, supporting standard industrial M.2 WiFi 6 modules.
ArmSoM recommends using RTL8852BE, AP6256. Installed in the ArmSoM-W3 M.2 E slot and then it can get online after wifi setup.

Use v4l2-ctl for image capture

armsom@armsom-w3:/# v4l2-ctl -d /dev/video11 --set-selection=target=crop,top=0,left=0,width=2112,height=1568 --set-fmt-video=width=2112,height=1568,pixelformat=NV12 --stream-mmap=3 --stream-to=/nv12.bin --stream-count=1 --stream-poll

Use gst-launch-1.0 for direct video recording

armsom@armsom-w3:/# gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=2112,height=1568, framerate=30/1 ! xvimagesink

Notes

[Electrostatic Protection]

Before handling the device, please ensure you wear an anti-static wrist strap or take electrostatic discharge measures to prevent damage to the development board.
Assembly should be performed in an electrostatic-safe environment, avoiding operations in dry and low-humidity conditions.
When not in use, store the device in an anti-static bag and keep it in a suitably temperature-controlled, low-humidity environment to prevent static electricity buildup.
When handling the device, avoid friction or collisions to prevent the generation of static electricity that could cause damage.
When holding the device, try to avoid direct contact with the chips on the mainboard to prevent static damage.
Do not plug or unplug wires or other devices while the device is operating to avoid damage from electrical surges.
When connecting or disconnecting the GPIO/MIPI expansion interfaces, make sure to turn off the power and disconnect the power cable to prevent damage from electrical current.

[Heat Management]

Without effective cooling measures, the surface temperature of the main chip may exceed 60 degrees. When handling the device, please avoid direct contact with the SoC and surrounding power inductors to prevent burns. Ensure that the environment is well-ventilated during operation to prevent localized heat buildup, which could lead to overheating. Additionally, do not place the device in direct sunlight. It is recommended to choose between the official cooling fan, heat sink, or third-party cooling kits based on specific usage conditions to ensure optimal cooling performance.
