The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi frontend (both as client and access point) and TCP/IP stack with DNS support as well. We do sell these on a breakout, but maybe you wanna just put this in your own project PCB. As of Dec 1 2016, we are shipping the ESP-12S version which no longer has the SPI flash pads brought out on the bottom row. Note that you couldn't use them for GPIOs or anything, they were there so you could program the FLASH chip only. These modules are very easy to hand solder, with big pads! We have this part in the Adafruit Eagle library (ESP12) - the extra pads don't appear but they are not usable anyways. Comes with 4MB flash chip, ESP processory, and onboard antenna. These come preprogammed with the NodeMCU Lua firmware, so you are ready to rock. Some extra parts will be needed to get this going, check out the HUZZAH schematic for the extra components we recommend For advanced users only! This product is just the module - which can be difficult to use. Click here if you're looking for the Huzzah ESP8266 Breakout!
