WIFI CHIP

The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the add modules to an existing device networking or building a separate network controller.

The removed pads(bottom row of ESP-12) contained mainly IO pins that could not be used by the user anyway, so it does not affect the usability of the board. The remaining pins are 100% pin-compatible with the ESP-12F and ESP-12E modules. You can solder this module onto a board designed for the ESP-12E or ESP-12F board.

Ai Thinker ESP-07S ESP8266 Serial WiFi Module uses the very popular ESP8266 chip. The software can be developed using many different platforms, like Arduino for example. The pads on this module have an easy to hand solder 2.0mm pitch.
