UWB is a Unit which integrates the UWB(Ultra Wide Band) communication protocol which uses nanosecond pulses to locate objects and define position and orientation. The design uses the Ai-ThinkerBU01 Transceiver module which is based on Decawave's DW1000 design. The internal STM32 chip with its integrated ranging algorithm,is capable of 10cm positioning accuracy and also supports AT command control. Applications include: Indoor wireless tracking/range finding of assets,which works by triangulating the position of the base station/s and tag (the base station resolves the position information and outputs it to the tag).

The firmware currently carried by this Unit only supports the transmission of ranging information, and does not currently support the transmission of custom information. When in use, it supports the configuration of 4 base station devices (using different IDs), and only a single tag device is allowed to operate at the same time.

    Ultra-Wideband (UWB) Unit Indoor Positioning module (DW1000)

    Great product for technology evaluation

    I ordered 4 units for a prototype work. Shipping was fast and it work as advertised. To get 100% accurate reading, 5 units are required (4 Anchors & 1 Tag). It was my mistake to order only 4 units.
    My only concern is when powered using Core2 controller, battery get drained very quickly (5-8 min). Anchors can be externally powered. But the running time of the Tag is bit concerning (this can also be solved by connecting a mobile battery to Core2 controller.

    Research has not yet started on the project that this device will be used for so I am unable to judge its performance at this time, but I'm sure it will work fine.
