Hello,
After unsuccessfully trying the UART WIFI suggested by this website, mainly because of power issues though I could have it to work and run for a little while, I tried another UART WIFI which seems much, much, much more reliable and user friendly since it has its own AP mode which allows you to configure it through web interface directly (you do not need to connect it to USB TTL module) and a quite efficient factory restoration process in case you input the wrong settings.
The model hardware name on Amazon is "Embedded Wifi To Serial Module RS232UART WIFI Board Module External Antenna"
I can get a connexion to EZB using both methods : typing directly the IP address + port into ARC's connection or through serial emulation.
However, when I use serial emulation (HW virtual serial port) I get a repeating message such as : "Disgard incoming buffer (This should never happen)"
And if I connect through IP address directly I get something really weird : it says that I have to upgrade the EZBoard firmware and, most of all, it shows different versions numbers : 24.x , 14, 17...
Here is the full debug report in cas God (DJ) took a look at it. I remember someone had ordered the same device so I'm posting this in case he found the proper settings. I set the module to 9600 bauds, TCP server mode. Let me know if you need more details.
Here is the debug report.

You have to connect your computer wifi to the module. It appears as an adhoc network. You may find all details in the manual.
It was the power. For some reason I can't power it from the EZB.
@elfege Sorry to bother but could I ask you to post screenshots of all your settings in the wifi WEB app config?
Just look back in the history of this thread, there are screenshots posted already. For the power, you must power it from 3.3v port, just where the bluetooth took its power from. It works for me.
I have seen those screenshots but I must be missing something as it is not working for me. I would really appreciate a full set of screenshots so that I might easily and quickly find the issue.
What is not working exactly ? Can you access the web interface ? Have you double or even triple checked your connections ? As I said in a previous post you must connect TXD to TXD and RXD to RXD and not, as it is usually supposed to be, TXD to RXD.
Use the doc named USR-WIFI232-X-V4-en.pdf in the cd-rom provided with the device. It shows all the screenshots you need.
Best, Elfege
For info : TXD pin is the one right above the ground pin on the wifi module.
Sorry : you may need to read two docs : USR-WIFI232-start-en.pdf for the screenshots and web config ; and USR-WIFI232-X-V4-en.pdf for all technical details such as pins labels, etc.
