Pin Assignment Compatibility Siemens MC55 / EZURiO
WISMC02BI and WISMC04BI
Overview
This document provides a comparative view of the pin assignments between
the Siemens MC55 GSM / GPRS Module and the EZURiO Wireless LAN
Module.
This document is to be used as a guide for pin compatibility between the two
modules, for full details of the physical dimensions and module functionality
please refer to the relevant module datasheet.

Pin assignment EZURiO WISM MC55
All unused pins on the EZURiO Wireless LAN module are floating connections
and are not affected by voltage or signals if the module is used as a direct
replacement for the Siemens MC55 GSM / GPRS Module.
