Setting up the evaluation board
2.1
Evaluation board setup
The EVK-NINA-B311/EVK-NINA-B312 will be delivered with the u-blox connectivity software installed
on the module.
Before connecting the module, download and install the latest u-blox s-center evaluation software
from the u-blox website.
To use Bluetooth Low Energy on the EVK-NINA-B311/EVK-NINA-B301, connect a 2.4 GHz antenna to
the U.FL antenna connector (J10). The EVK-NINA-B312/EVK-NINA-B302 has an onboard antenna.
Plug in either an external power supply in J5 connector or connect to a USB host with a USB cable
attached to J8 connector. You can also power the evaluation board with a CR2032 coin cell battery.
The status light (
DS6
) will turn green, indicating it has power. The NFC antenna can be connected to
the J11 connector.
⚠
Be careful to check polarity before connecting an external power supply to the EVK-NINA-B3
evaluation board. Center conductor is positive (+) and the ring is negative (-).
The operating system will install the correct drivers automatically. The drivers will only need to be
installed the first time you connect the unit to a new computer.
⚠
If the drivers are not installed automatically, download the nRFgo Studio from
to get the Jlink CDC UART driver.
A COM port will automatically be assigned to the unit by Windows. Do the following to view the
assigned COM ports on Windows 7:
•
Open the Control Panel and click Hardware and Sound.
•
Click Device Manager in Devices and Printers. This will open Device Manager window where you
can view the assigned COM ports.
To view the assigned COM ports on Windows 10, right-click on the Windows Start button and select
Device Manager.

Starting up
2.2.1
EVK-NINA-B311 and EVK-NINA-B312
Perform the following steps to enable communication with the module:
1.
Start the u-blox s-center evaluation software.
2.
Use the default baudrate 115200, 8N1 with flow control.
3.
You will now be able to communicate with the module through AT commands.
For a list of available AT commands, see the u-blox Short Range AT Commands Manual [3]. To get
started with basic use case set up of the EVK-NINA-B3 with u-blox connectivity software, see the
NINA-B31 Getting Started [5].
2.2.2
EVK-NINA-B301 and EVK-NINA-B302
If you would like to use the EVK-NINA-B3 together with Nordic Semiconductor SDK, refer to the
Software section of the NINA-B3 System Integration Manual [2].
