This is a general purpose wifi enabled board. It can read and write information via wifi for example over telnet or it can be used directly via a serial interface. The wifi can contact external sources if required and also given the correct network environment can be controlled externally.
The board is intended to be used in a system that will issue serial commands to it. However it can also run stand alone and be re-programmed over the wifi if required.
The board comes with an antenna and USB to serial for initial set up.

The board is controlled serially through the wifi interface using telnet or similar using simple commands. Because of the wifi link there is no need for a physical connection to the main controller. In addition the controller does not need to be physically near the board. The wifi also has access to the internet via the connected router and so has access to any internet resource.
Full details of the board with commands and use
Control from a Raspberry Pi without the need for connecting anything to the Pi. Control remote locations via the internet. Use with horticulture, temperature probes, motor controlled ventilators, relays for power. Boiler control for central heating.
Because the board can be programmed, this can be carried out in situ over the wifi interface. There is no need to uninstall it from an applications. If a bug is found at a remote site then the re-programming can be done back at base.
