The Telit EVK2 is a tool for:
- Developing applications based on current
and future Telit GSM/GPRS, UMTS/HSDPA,
and CDMA module families via AT commands
through serial ports
- Programming and updating of all
Telit modules
- Debugging Telit-module-based applications
- Implementing simple applications
(stand alone function) by executing scripts
using a Python interpreter equipped module
without the need fo an external microprocessor
RS-232 / USB 1.1 serial ports
The communication between the
application and the Telit module is done
through Asynchronous Serial Interfaces
board as a double stacked standard DB9
connector providing two serial communication
ports (RS-232 up to 115 Kbps).
Alternatively, this communication can be
done through a CMOS HUB, which provides
two-way communication compliant to USB
1.1 specifications at higher data rates
(up to 1,5 Mbps). The USB connection is
provided through a USB-A USB-B cable.
Serial port selection is made through configuration
of jumpers on the motherboard.
Power supply inputs
The EVK2 is equipped with different power
supply inputs enabling its use it in the following
environments:
- Automotive setup:
5 to 40 Volt supply
- Laboratory setup:
+ 3.8 Volt fixed supply
- Portable setup:
Rechargeable Li-Ion battery pack

General purpose inputs / outputs
With the EVK2, all general purpose
inputs/outputs are made accessible on
the adapter boards by a set of pins on the
PTH-type connector.
This allows developers to build their own
interface boards best suited for their
requirements, e.g. custom connectors,
cables, relays, LEDs, etc.
