Setting up the evaluation board
2.1
Evaluation board setup
The EVK-ANNA-B112 will be delivered with u-blox connectivity software installed.
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-ANNA-B112, connect a 2.4 GHz antenna to the U.FL
antenna connector (J10). The EVK-ANNA-B112C 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. Both ways of board connection are possible, rotation of 180 degrees.
⚠
Be careful to check polarity before connecting an external power supply to the EVK-ANNA-B112
evaluation board. Center conductor is positive (+) and the ring is negative (-).
The very first time you connect the unit to a new computer, drivers need to be installed. The
operating system should handle this automatically.
⚠
If the drivers are not installed automatically, download the nRFgo Studio from
www.nordicsemi.com
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.
