5 Evaluation Kit EVK-PRO3
80312ST10046A Rev. 1 - 03/10/08
In order to assist you in the development of your Telit GE863-PRO3 and WE865-DUAL module
based application, Telit can supply an Evaluation Kit EVK-PRO
3
with appropriate power supply, SIM
card holder, RS232 serial port level translator and USB host & device, SD Card holder, Ethernet and
antenna connection.
The development of the applications utilizing the Telit GE863-PRO
3
and WE865-DUAL module must
present a proper design of all the interfaces towards and from the module (e.g. power supply, audio
paths, level translators), otherwise a decrease in the performances will be introduced or, in the worst
case, a wrong design can even lead to an operating failure of the modules.
In order to assist the hardware designer in his design phase, the EVK board presents a series of
different solutions, which will cover the most common design requirements on the market, and which
can be easily integrated in the OEM design as building blocks or can be taken as starting points to
develop a specific one.
