That looks like the older revision that uses the ESP-12 module rather than an ESP-12E. But yes, it does 802.11b/g (don't think it does n), with a pretty full IP stack. It'll run both LUA as part of the NodeMCU project, and it'll also do C/C++ natively with the arduino project also supporting it as a board directly. EDIT: Here's a board with the ESP-12E http://www.ebay.com/itm/NodeMcu-Lua-WIFI-Internet-Things-development-board-based-ESP8266-CP2102-module-/400923947498?hash=item5d58edf1ea:g:U1EAAOSwymxVRzWC http://www.ebay.com/itm/NodeMcu-Lua-WIFI-Internet-Things-dev... It has some more flash and more pins broken out compared to the ESP-12 Also once you've got something build you can buy the bare modules for usually <$3 and they don't need much support hardware to use, just a 3.3 volt regulator. The ESP-12/E modules however use a 1mm pitch rather than 2.54mm pitch that you usually find on breadboards, so they are a bit more difficult to setup initially if you're doing it bare.
