Introduction
The WI04 module provides designers with a ready made component that provides a fully integrated solution for applications, using the IEEE802.11 standard in the 2.4-2.5GHz ISM frequency band, including 802.11b/g/n and also provides IEEE802.3, can be quickly and easily included in product designs. The modules integrate all of the RF components required, no need to perform expensive RF design and test. Products can be designed by simply connecting sensors and switches to the module IO pins or UART interface. The modules use ralink’s chip Wireless MCU , allowing designers to make use of the serial interface to connect with their device Hence, this module allows designers to bring wireless applications to market in the minimum time with significantly reduced development effort and cost.
This product is an embedded module based on the universal serial interface network standard,built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions. Through the WI04 module, the traditional serial devices do not need to change any configuration; data can be transmitted through the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet. Also the Wi04 module have FCC modular approvals and is compliant with EU regulations.

Very good quality of the boards, all pins are labeled.
The board has USB pins, so may be OpenWRT firmware can access USB.
Sometimes it is a bit confusing when needed to restore factory settings, indication of reset is poor.
Be aware, when you set up it into WIFI CLIENT mode,password for selected network appears in the password field (default 12345678) – change it corresponding to your network!
After all, very nice device for experiments.

Very useful thing!
I bought 2 of these and was able to transfer serial data between two apparatus in different cities. I connect each module to local AP and transfer uart data via the Internet.

Be careful when buying antennas for Core board!
My advice: buy a kit for the first time, or core board with PCB antenna. Because there is no exact information, if the antenna and ipex-sma adapter has SMA-female, or SMA-male connector. Also there are RP-SMA connectors (Reverse polarity.. RP-SMA-Female=SMA-Male..)
If you buy core board, it is useful to buy mm to 2.54 pitch dupont cable adapter (Electrodragon sells it also).

Does the board has 16m or 32m of ram? Hilink has a 32m version now and with 16m openwrt runs quickly out of memory.
