1 Overview

The scope of this document is the description of some hardware solutions useful for developing a product with the Telit GE863-PRO3module.

In this document all the basic functions of a M2M device will be taken into account; for each one of them a proper hardware solution will be suggested and eventually the wrong solutions and common errors to be avoided will be evidenced. Obviously this document cannot embrace the whole hardware solutions and products that may be designed. The wrong solutions to be avoided shall be considered as mandatory, while the suggested hardware configurations shall not be considered mandatory, instead the information given shall be used as a guide and a starting point for properly developing your product with the Telit GE863-PRO3module. For

further hardware details that may not be explained in this document refer to the Telit GE863-PRO3Product Description document.
