☞
The pins / interfaces that are not supported by a specific LENA-R8 product version should not be
driven by an external device. For the features supported by each LENA-R8 product version, see the
LENA-R8 series data sheet
1.7 Software installation
The LENA-R8 USB drivers for Windows OS are available with the EVK-R8. Download the executable
file from
www.u-blox.com
running the executable.
1.8 Board setup
1.
Insert a SIM card into the SIM card holder (J300 on the EVB).
2.
Connect the cellular antenna provided with the EVK-R8 evaluation kit box to the cellular antenna
SMA connector on the ADP-R8 (ANT, RF input/output for transmission and reception of LTE/2G
RF signals)
3.
For LENA-R8001M10, connect the GNSS antenna provided with the EVK-R8 evaluation kit box
to the GNSS antenna SMA connector on the ADP-R8 (ANT_GNSS, RF input for the reception of
the GNSS RF signals). Place the GNSS antenna in a location with a good view of the sky.
4.
For LENA-R8001, if it is required to use the GNSS functionality of the MAX-M10S GNSS module
mounted on ADP-GNSS, connect the GNSS antenna provided with the evaluation kit to the GNSS
antenna SMA connector on the ADP-GNSS. Keep the cellular GNSS detach switch (SW304) in
"GNSS" position. Place the GNSS antenna in a location with a good view of the sky.
