WIFI-2-IA is an Ogemray GWF-3M08-33-B-7-1 OEM WiFi Module designed to use a USB2.0 port on a 3.3V system. It has a Ralink/MediaTek RT5370N WiFi module and a PCB antenna for short-range operation (2 or 3 meters). Its 7-pin interface at 2mm pitch allows it to be connected to an Arietta-128MB or Arietta-256MB embedded Linux module (a header socket is included that you can solder to your Arietta so you can plug in this WiFi module).
You could use a 2mm-pitch prototyping board to build this into your own design.
This is not an end-user USB WiFi module! It is designed to be embedded into a device that would provide the actual USB port.
If the short-range PCB antenna is not sufficient for your project, consider the WIFI-2 which has an external antenna connector.

Using WiFi Module on Arietta G25 The Arietta boards have a 7-pin through-hole header designed to support this module, and the Ralink Kernel driver is already installed in the default microSD image for Arietta (see link below for configuration instructions).
Note that the Activity LED on the WiFi module is not connected on Arietta boards. Also note that the module uses Arietta's USB port B signals on J4.16 (D+) and J4.18 (D-), so those pins can not be used for other purposes when this module is installed.
