The u-blox Explorer XPLR-AOA-1 kit contains an antenna board with a u-blox NINA-B411 Bluetooth Low Energy module, a transmitter tag with a NINA-B406 Bluetooth Low Energy module, and the u-connectLocate address-finding software. The software runs directly on the Nordic Semiconductor nRF52833 SoC integrated into the NINA-B411 module and calculates the angle of arrival (AoA) of incoming signals without any additional processing.
Engineers can create a complete positioning system by combining several XPLR-AOA-1 kits and triangulating the directions of three or more antenna plates. Applications include, for example, detecting if a person or object is approaching a door, avoiding collisions between moving objects, and directing a camera to a moving tag.
