Product description
Documentation & resources

The ANT-B10 is a compact antenna board designed specifically for Bluetooth angle of arrival (AoA) direction-finding systems. It features eight patch-antenna elements in an arrangement that offers optimal performance in the presence of multipath effects. It measures the angle of an incoming Bluetooth Low Energy (LE) radio signal with high accuracy, and in conjunction with at least two more ANT-B10 boards and positioning engine software, it can determine the precise position of a Bluetooth LE device in an indoor environment.

ANT-B10 features the NINA-B411 Bluetooth 5.1 standalone module, programmed with the u-connectLocate software, which implements the unique u-blox direction-finding algorithm. It includes a widely available standard pin header that provides a digital interface to the application board, thus forming a complete AoA anchor point. Alongside the EVB-ANT-1 development platform (part of the XPLR-AOA-3 kit), the user can plug the two boards together and have an AoA anchor point within seconds.
