Ultra Wide Band technology is a game changer for indoor positioning. This is an upgraded ESP32 UWB with almost 3x the range of normal UWB.
Makerfabs did a good job addressing the range issue in the orginal version.
I have made a video about the first version here: https://lnkd.in/gdpnFd9B

New version is going to be released soon.
