Create PIC circuit interface with GSM and GPS

PCB design

Create module for IC SPX29302

These module used to regulate the voltage from the USB port and supply 3.3V to module FT232BL.
The advantage of these IC is it can adjust the output voltage.

Create module for IC FTDI232

the problem on 6/10/2010 occur because the PCB design for these IC connect proper to the wire.
to solve these problem, make the module drawing and link to the PCB drawing by using protues software.
The IC module as figure above.

The step to make these module using protues:

1. Open the protues software.
2. Make a box and pin connection.
3. Make a devide after complete drawing.
4. Key in all the data for the module.
5. Add the PCB drawing.
6. Check pin number on the module and PCB drawing.
7. done.
