2 Functional description
The evaluation board offers the user the possibility to develop hard- and software for the
compatible radio module. It can be connected to an USB port of a PC.
For the connection to a micro controller system the development board is equipped with a
multi-pin connector which is connected to all pins of the RF module. Jumpers allow the mod-
ule to be disconnected from components such as the USB interface which are not required.
Feel free to check our youtube channel:
www.youtube.com/user/WuerthElektronik/videos for video tutorials, hands-ons and webina-
rs relating to our products.
2.1 Taking into operation
To run the evaluation board place the jumpers on default location as shown in figure 3 .
The corresponding FTDI driver package (www.ftdichip.com/Drivers/VCP.htm) has to be in-
stalled on your PC.
Connect the power jack or external power supply to the EV board and make sure the VDD
is stable and able to reliably supply the module’s static and peak current consumption as
specified by the module manual.
The next step is to connect the evaluation board to the PC using a USB-cable. In that way a
COM port can be detected and installed on your PC. Check the device manager to acquire
the COM port name of the EV board. A typical name is "COM12" in Windows systems or
"/dev/ttyUSB0" in Linux systems.
The WE-SmartCommander or any other serial terminal program (like hterm for Windows)
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 USB jack or an al-
ternative power supply, the reset button should be pressed to ensure a clean start-up of the
module.
Please refer to the module reference manual to get the detailed module specific quick start
instructions.

3.4 Buttons
Figure 7: Buttons
3.4.1 RESET button
Internally the active low reset input of the micro processor is connected via a RC combination
with the power supply to ensure a proper startup of the module. Any module provides a
PROTEUS-III/THYONE-I Evaluation board user manual version 1.4 © February 2021
www.we-online.com/wireless-connectivity 16

/RESET pin that is connected to this button so the module can be restarted properly. Most
modules provide an internal pull-up resistor. Please refer to the module specific manual for
detailed information.
3.4.2 WAKE-UP button
Some modules use the wake-up button connected to their WAKE-UP pin to exit from sleep
mode of the module. Please refer to the module specific manual for detailed information.
3.5 Function blocks
3.5.1 Power supply
3.5.1.1 Bus powered, power supply through USB
The development board can be run via USB. The integrated voltage regulator regulates the
connected USB voltage 5V down to 3V and supplies the remaining parts of the circuit. If the
evaluation board is power sourced the power Power LED lights up.
3.5.2 JP1 - Current measurement
By default, JP1 is bridged for normal operation. If a current meter is connected in place of
the jumper, the power consumption of the radio module can be measured.
If the meter is not attached and the bridge is not set, the module will not receive a supply
voltage. However, the power Power LED may be active, as it is connected prior to the current
measurement bridge in order not to distort the module’s power consumption.
3.5.3 UART / USB
The UART of the module can be connected to the USB converter by setting the bridge JP2.
In this case it is available on the USB jack. Using the FTDI-driver the PC will show a virtual
COM-Port which can be used to communicate with the module.
The USB cable length must not exceed 3 meters.
3.5.4 UART direct
If a micro-controller is to be connected to the module, remove the bridges on JP5. The
UART can be connected directly on the pin strip JP5 (all odd numbered pins). The module
RXD line must be handled accordingly by your host (i.e. pulled up while inactive and during
module boot-up).
Beware of IO level incompatibility. The host must obey the values stated in the module’s
manual. Especially the IO level restrictions must be implemented by a host system (i.e.
using a level shifter to use the allowed IO levels).
PROTEUS-III/THYONE-I Evaluation board user manual version 1.4 © February 2021
www.we-online.com/wireless-connectivity 17

3.5.5 LFXO crystal
For higher LFCLK accuracy (better than ±250ppm) a low frequency crystal oscillator of
32.768kHz (LFXO) shall be used. A crystal, 3.2 ×1.6mm package, for example 830009706,
can be placed on the evaluation board to position Q1. The needed load capacitance can be
reached with capacitors C9 and C10, 0402 package.
nRF52840 pin P0.00/XL1 and P0.01/XL12 are connected to module pad LED_1 and LED_2
respectively. If a LFXO is mounted to the EV board the JP2.7-8 and JP2.9-10 jumpers shall
not be connected, therefore the LED1 and LED2 function is no longer available.
Figure 8: LFXO mounting
The input capacitance of the pad LED_1 and LED_2 are 4pF. The values of C9 and C10 can
be calculated as follows.
The load capacitance of LFXO is given by
Cl=C9l∗C10l
C9l+C10l
(1)
If C9l=C10l= C, then
Cl=C
2(2)
whereas,
C9 = C−CXL1−CP CB (3)
C10 = C−CXL2−CP CB (4)
Cl= Load capacitance of LFXO crystal.
CXL1= Input capacitance of Pad LED_1 (4pF)
CXL2= Input capacitance of Pad LED_2 (4pF)
CP CB = Parasitic capacitance of PCB Parasitic capacitance of the PCB can vary depending
on design and track length. It can vary from 0.5pF to 2pF.
For the crystal 830009706 with load capacitance of 9pF and parasitic capacitance of 2pF.
The value of C9 and C10 results in 12pF which was also tested on the evauation board.
Depending on parasitic capacitance of Host PCB, a capacitance of 12pF may be a good
starting value for C9 and C10.
