Evaluation Kit
EVK2
for Telit GSM/GPRS-Modules
The Telit Evaluation Kit EVK2 provides a ready, future-proof and flexible environ-
ment for a quick and easy development of applications with Telit’s GSM/GPRS
Modules families, dramatically reducing the time-to-market.
The kit is formed by a motherboard, on top of which an adapter board with the
related module is plugged. This concept allows using it across the boundaries of
various form factors and product generations, also in future.
On the motherboard are placed all basic interfaces, like several power input
facilities, SIM holder, audio monitor outputs, 2 x RS232 and USB 1.1, as well as
Reset and ON keys, representing a reference design for this peripheral circuitry
of the module. Jumper settings define the routing of the serial interfaces, audio
signals and power supply. The PC or DTE sending and receiving information
over the AT-Command interface can be connected to a USB or RS232 socket.
Adapter boards convert the connection technology of the module (board-to-
board or BGA solder) into a PTH pin connector. The part of the basic interfaces
is served by the motherboard, whereas specific interfaces according to the type
of the module (antenna, general purpose inputs/outputs (GPIO), ADC/DAC,
UART etc.) are available on the adapter board to connect to the user’s applica-
tion, extension boards or other development tools or measurement equipment.
An extension board allow connecting a VGA Camera component which is directly
supported by the Telit modules is available.

The Telit EVK2 is a tool for:
■ Developing applications: based on actual and
future Telit GSM/ GPRS Modules (cellular
modems) by means of AT commands through
the serial ports
■ Easy programming and updating: of all
Telit Modules
■ Debugging Telit Module applications
■ Implementing simple applications
(stand alone function) by executing a script
over a Python interpreter without any
external microprocessor
