PIC processor board with integrated WiFi module

Hi All,

Working on a project that requires extending communications over a long distances, the repeater stations are powered via Solar/Battery. Each repeater point will also have 2.4Ghz WiFi router or possibly an ethernet port.
I'd like to know the state of the battery/solar and maybe collect some other telemetry data like temperature.
Project is low volume and not wanting re-invent the wheel in hardware design.

Can anyone recommend an already developed board with a microchip processor that has some D I/O, analogue input and integrated WiFi controller chip?

Thanks,

Rob.
