Figure 2: Block diagram of the EVK-R5 for SARA-R5 modules
The EVK-R5 evaluation kit is formed by three boards:
1.
The lower one, called EVB-WL3, contains the power supply and other peripherals for the u-blox
SARA-R5 series cellular module (such as SIM card holder, reset button and power-on button).
2. The cellular adapter board, called ADP-R5, contains the u-blox SARA-R5 cellular module, antenna
connectors for the cellular RF interface and the GNSS RF interface1 of the SARA-R5 module, USB
connectors for the two UART interfaces and the USB interface of the SARA-R5 module, and the
DIL header connectors (J300 and J301) making accessible interfaces of the SARA-R5 module.
3. The GNSS adapter board, called ADP-GNSS, contains the u-blox GNSS module, the GNSS
antenna connector and the USB connector for the GNSS module.
The cellular and the GNSS adapter boards are connected by means of male header board-to-board
connectors provided on the bottom of the adapter boards and their corresponding female connectors
provided on top of the lower board, called EVB-WL3.
If the on-board / B2B switch (SW401) is set to “on-board”, then the single UART interface (with the
default USIO variant 0 setting, or the USIO variant 1 setting) is available on DIL connectors on the
cellular adapter board. It is routed up to the RS232 DB9 connector (J500) or the USB connector (J501)
mounted on the EVB-WL3 board according to the settings of the mini-USB / DB9 switch (SW403).
If the on-board / B2B switch (SW401) is set to “B2B”, then the two UART interfaces (with the +USIO
variant 2, 3 or 4 setting) are available on the USB connector (J201) mounted on the cellular adapter
board.
The USB interface of the cellular module (available for diagnostic purpose only) is available on the
native USB connector (J105) mounted on the cellular adapter board.
Other SARA-R5 series peripherals are available on the dual-in-line male board-to-board connectors
provided on the top layer of the cellular adapter board (J300 and J301), which are pin-to-pin
compatible to the connectors on the bottom layer of the adapter board.
The lower board (EVB-WL3) is also designed to be used with other u-blox cellular adapter boards. It
contains additional switches, jumpers, connectors, LEDs and parts that may be only partially
described in Figure 1 or in this document, because they are intended for use only with other u-blox
cellular modules. It is recommended to leave any additional connector unconnected and any additional
switch in its default configuration.

1.
Insert a SIM card into the SIM card holder (J300 on the EVB-WL3).
2. Connect the cellular antenna provided with the evaluation kit box to the Cellular antenna SMA
connector on the ADP-R5 (ANT connector for transmission and reception of LTE RF signals)
3. If the GNSS functionality is required:
3.1. For the EVK-R500S and EVK-R510S, connect the GNSS antenna provided with the
evaluation kit box to the GNSS antenna SMA connector on the ADP-GNSS (J208); keep
cellular GNSS detach switch (SW304) on “GNSS” position.
3.2. For the EVK-R510M8S, connect the GNSS antenna provided with the evaluation kit box to
the GNSS antenna SMA connector on the ADP-R510M8S (J112); keep cellular GNSS detach
switch (SW304) on “detach” position.
Place the GNSS antenna in a location with a good view of the sky.
4. Connect the AC / DC +12 V power adapter provided with the evaluation kit box to the 9 – 18 V
power input connector (J400 on the EVB-WL3). The LED DL401 lights blue.
5. Be sure to provide a jumper socket on both the Cellular VCC supply jumpers (J404 on the
EVB-WL3, and J109 on the ADP-R5). These jumpers provide the connection from the 3.8 V output
of the supply circuit on the EVB-WL3 to the VCC input of the module.
6. To enable the board power supply, turn the Main power switch (SW400 on the EVB-WL3) to the

D Current consumption measurement
The current consumption of SARA-R5 series modules can be measured on the EVK-R5 by removing
the jumper socket from the Cellular VCC supply jumper J109 available on the ADP-R5 board, as shown
in Figure 5.
Cellular VCC supply jumper socket (J109)
to be removed for SARA-R5 module
current consumptionmeasurements
Figure 5: Jumper socket to be removed for SARA-R5 series modules current consumption measurement
A suitable external digital multi-meter (as for example the Keysight/Agilent 34465A, 34410A or
34411A) can be used for current consumption measurements. In this case, the 3.8 V supply circuit on
the EVB will supply the SARA-R5 module mounted on the adapter board, with the digital multi-meter
placed in series as illustrated in Figure 6.
