Explorer kit aids Bluetooth 5.1 direction finding

In stock at distributor Mouser Electronics is the XPLR-AOA-1 Explorer Kit from u-blox.

The new kit makes it easy to evaluate the potential of Bluetooth 5.1 direction finding and high-precision indoor positioning to enable applications such as access control, collision detection, smart appliances, and asset tracking.

The u-blox XPLR-AOA-1 Explorer Kit is an antenna board with a u-blox NINA-B411 Bluetooth Low Energy module, transmitter tag with NINA-B406 Bluetooth Low Energy module, and u-connectLocate direction-finding software.

The software runs directly on the NINA-B411 module’s embedded Nordic Semiconductor nRF52833 system-on-chip (SoC), calculating the angle-of-arrival (AoA) of the incoming signals with no additional processing required.

Engineers can create a full positioning system by combining several XPLR-AOA-1 kits and triangulating the directions from three or more antenna boards.

Applications include detecting whether a person or an object is approaching a door, avoiding collisions between moving objects, and directing a camera at a moving tag.
