 This is WiFi serial transceiver module, based on ESP8266 SoC.  The SOC has Integrated TCP/IP protocol stack.

This is the latest upgraded version of ESP-01 (ESP-01E) with 1M Flash

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
 
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

54Mbps (3/4 64-QAM)    -75   dBm
HT20, MCS7 (65Mbps, 72.2Mbps)     -71   dBm

OFDM, 6Mbps   37   dB
OFDM, 54Mbps   21   dB

Note: For normal operation, Vcc and CH_PD (chip enable) pins are tied to 3.3V with GND to 0 V, and TX and RX pins connected to your serial interface of choice (Arduino, FTDI USB interface, etc.). As the module operates at 3.3v, if your serial interface operates at 5v, you will need a level converter in the module’s RX line to prevent over-voltage. A simple resistor divider (1kΩ and 2.2kΩ) or resistor and 3.3v zenner will do the trick. For better performance, use a FET level shifter in both RX and TX lines.

The module is the cheapest way to integrate/connect your project with any WiFi enabled device or IoT. -Please update the description. The module does have two on-board LEDs, RED one for power indication and BLUE one for data transfer indication. Initially I was informed that there are no LED indicators on-board. - Since it needs 3.3V and a max of 200mA current, I would suggest everyone to buy this module along with it: https://www.fabtolab.com/3.3V-power-supply - The module cannot be directly fixed on a breadboard so you would need to make an adapter for it (which is very easy). Here is a detailed video tutorial on how to make it: http://youtu.be/GhwmgvcjRaA
