Product Description
The Telit Evaluation Kit (EVK2) provides a robust, future-
proof and flexible environment to streamline all application
development based on Telit GSM | GPRS, UMTS | HSPA,
CDMA 1x | EV-DO, LTE, CatM and NB IoT module families,
significantly reducing time-to-market.
The kit includes a motherboard and an adapter board
where the target module is connected. This concept allows
the EVK2 to be used across various form factors and prod-
uct generations, both present and future.
The motherboard includes the basic interfaces such as
power input, SIM card holder, audio monitor outputs,
RS-232, and USB; as well as a Reset button and power
switch. The circuit implemented in the EVK2 motherboard
is based on the recommended reference design for the
module’s peripheral components and I/O connections.
Adapter boards are available for all the different module
families. Adapter boards for modules with board-to-board
connectors may be used for development with a number of
different target modules sharing the same form factor.
Key Benets
The Telit EVK2 is a tool designed for engineers, program-
mers, and developers who are looking to:
• Develop and test applications based on current and
future Telit GSM | GPRS, UMTS | HSPA, CDMA 1x | EV-DO,
LTE, CatM and NB IoT module families via AT commands
through serial ports
• Program and/or update any Telit module
• Debug and/or Improve applications based on
Telit modules
• Implement simple applications (stand alone function)
by executing scripts with an IoT AppZone equipped
module without the need for an external microprocessor
• Develop a first-pass proof-of-concept device
for a new application

Product Features
• Develop and test applications based on
current and future Telit GSM | GPRS, UMTS
|HSPA, CDMA 1x/EV-DO, LTE, CatM and NB
IoT module families via AT commands
through serial ports
• Program and/or update any Telit module
• Debug and/or Improve applications based on
Telit modules
• Implement simple applications (stand alone
function) by executing scripts with a Python
interpreter-equipped module without the
need for an external microprocessor
• Develop a first-pass proof-of-concept device
for a new application without the need fo an
external microprocessor
• RESET & power ON button
• Battery charger control From Telit module
• OV protection on all input DC lines
• Reverse polarity protection on all
input DC lines
• 2 LED indicators
• SIM card holder
• Automatic mute control
Interfaces
• RS-232 / USB 1.1 serial ports
The application communicates with the Telit
module in the EVK2 through two asynchro-
nous serial interface ports (ASC0 and ASC1),
which are embedded in the motherboard as a
double stacked standard.
DB9 connector providing serial
communication (RS-232 up to 115 Kbps).
• Serial ports: 2 x RS-232 or 2 x USB
• Speaker output:
2 output power options:
- Option 1 - max 10mW / 16Ω on
standard 2.5 mm headset socket
- Option 2 - max 675mW / 8Ω on
PTH pin connector
• Microphone lines: 1x Single-ended (INT/EXT)
• Eearpiece output: 1x Single-ended (INT/EXT)
max 10mW/16Ω
• General purpose inputs / outputs
• With the EVK2, all general purpose inputs/
outputs can be accessed on the adapter
boards by a set of header pins on the PTH-
type connector.
This arrangement allows developers to build
their own interface boards best suited for
their requirements, e.g. custom connectors,
cables, relays, LEDs, etc.
• GPIOs (all available on the interface board)
Electrical & Sensitivity
• 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
