3. Plug the WB45NBT module into the 80-pin high-density Molex connector situated near the central
aperture on the BB45NBT Breakout board. Ensure that the 2 U.FL cables and SMA connectors are
passed through the aperture in the BB45NBT board.
4. Using the small Philips head jeweler’s screw driver, secure the WB45NBT using the 3 small Philips
screws to the BB45NBT board.
5. Using the nuts and washers provided, attach the respective SMA connectors on the end of the U.FL
cables to the apertures in the BB45NBT board marked BT_ANT and WLAN_ANT as shown in
Figure 1 .
6. Turn the BB45NBT board the correct way up and connect the dual band antennas with an SMA
connector to each of the BT-ANT and WLAN-ANT SMA connectors on the top side of the BB45BNT
board.
7. Connect the Wi-Fi and Bluetooth antennas to the male SMA connectors at the end of the 2 U.FL cables
connected in step 2 above.
8. You can power the BB45NBT from either mains power or the USB power socket. Figure 2 shows both
of these connectors and the power switch. Select which power supply you wish to employ:
a. DC Jack: Ensure the Power / USB Power switch is set to “From USB Port.” This is effectively the
“off” position if you’re intending to use DC power. Connect the power supply to the wall outlet
and put the barrel into the DC connector (J3) on the BB45NBT breakout board as shown in
Figure 2 .
b. USB Port: Ensure the Power / USB Power switch is set to “From DC Jack.” This is effectively the
“off” position if you’re intending to use USB power. Connect the USB A connector to your PC or
USB hub USB port. Connect the micro USB connector to the BB45NBT board USB power socket
shown in
Figure 2 . No LEDS should be lit on the board.
