Update on the wireless sensor project

We revised our board to include :

•  the wi-fi module
• three regulators for the 4V, 3.8V and 1.8V rails (the output voltage of the 4V regulator can be varied)
• more 100nF ceramic capacitors

We also made the tracks thicker.

The SIM548z GPS/GSM module will be going on the underside of the board, and the two antennae will be connected to the module via pigtail connectors. We are hoping to get the PCB by Monday the 9th.
