3 ANT-B10
The ANT-B10 antenna board provides a versatile Bluetooth® direction finding board equipped with
eight, dual-polarized, patch antennas for direction finding, as shown in Figure 4 and Figure 5.

The ANT-B10 antenna board hosts a single NINA-B411 Bluetooth Low Energy (LE) module, which
controls the antennas and applies an angle calculation algorithm to the received signals to compute
the tag angles. The angles are calculated by the u-connectLocate software running on the embedded
Microcontroller Unit (MCU) in the module. The angles are delivered over the UART port of the
ANT-B10. Future u-connectLocate software releases are planned to support USB and SPI interfaces.
