Family evaluation board user manual
2 Functional description
The Family Board is an intuitive, application oriented and cost effective EV board version to
evaluate a wide range of Würth Elektronik eiSos radio modules. It offers the user the possibility
to develop hard- and software for the corresponding radio module.
By default, the Family Board is assembled with pin headers to take the module into operation.
The necessary components shall be assembled by the user based on the need and application.
The Family Board is a balance for both experienced and non-experienced developers, as addi-
tional accessories and basic soldering skills are necessary to evaluate all the functions of the
radio module.
Out of the box, the board supports minimum test scope. With additional accessories and basic
soldering skills it is possible to enlarge test scope of the radio module.
Accessories required to test full scope of the radio module are:
• Additional assembly components listed in the table 8 and soldering equipment
• TTL-232R-3V3 FTDI cable [1]
All pins are available on pads where a pin header can be soldered in. The pins that are needed
for minimal pin configuration are available on already equipped headers, e.g. to connect a mi-
crocontroller or a PC and to set jumpers to choose operating modes of the radio module.
2.1 Taking into operation - PC
To use the TTL-232R-3V3 FTDI cable [1], the corresponding FTDI driver package [2] has to be
installed on the PC following the installation guidelines [3].
The TTL-232R-3V3 FTDI cable shall be connected to the pin header P1 of the Family Board.
It is important that the VDD is stable and able to reliably supply the module’s static and peak
current consumption, as specified by the module manual. A minimum board supply current of
50mA is necessary.
Incorrect orientation of TTL-232R-3V3 FTDI cable will damage the radio mod-
ule. For easy orientation, the pin number 1 and signals are labelled.
The next step is to connect the Family Board to the PC using the TTL-232R-3V3 FTDI cable.
In that way, a COM port can be detected and installed on the PC. In the device manager, the
COM port name of the TTL-232R-3V3 FTDI cable can be found. A COM port shall appear for
example: "COM12" in Windows systems or "/dev/ttyUSB0" in Linux systems.

WIRELESS CONNECTIVITY & SENSORS
Family evaluation board user manual
The WE-SmartCommander [10] or any other serial terminal program (like hterm [4] for Win-
dows) has to be run and the corresponding COM port has to be opened using the default
settings of the mounted radio module.
After the module is powered through the TTL-232R-3V3 FTDI cable or an alternative power
supply, the reset button should be pressed to ensure the correct functionality of the module.
The detailed module specific quick start instructions can be found in the corresponding radio
module user manuals [5, 6, 7, 8, 9, 11].
When taking the Setebos-I module into operation with the WE-
SmartCommander, either the Proteus-III or the Thyone-I module has to
be selected on the graphical user interface, depending on the jumper setting.
2.2 Taking into operation - Host controller
To take the Family Board into operation using a host controller, the pin header P1 shall be used.
An external power supply shall be connected to the Family Board. The power supply op-
tion 3 or 4 from the table 21 shall be used. It is important that the VDD is stable and able to
reliably supply the module’s static and peak current consumption, as specified by the module
manual. A minimum board supply current of 50mA is necessary.
The next step is to connect the communication lines of the module to the host controller. The
headers P1, P2 and P3 can be used to connect the module pins and host.
The detailed module specific quick start instructions can be found in the corresponding radio
module user manuals [5, 6, 7, 8, 9, 11].

3.3.6.1 Proteus-I/-II
For Proteus-I and Proteus-II modules the integrated antenna variant is assembled on the Family
Board.
For these radio modules, the use of the external antenna is not possible on the
Family Board.
3.3.6.2 Smart antenna
The so called "smart antenna" solution allows to use the external antenna or internal antenna
of the radio module just via mounting external components to the module.
By default, internal PCB antenna connection is used. In order to use an external SMA antenna,
2 pF capacitor (0402) on position C1 shall be populated. C2 shall be removed, C8, C11 and
C12 should be left unpopulated.
Optional: Experts have the possibility to use C1, C8 and C11 for additional
filtering or fine tuning.
