M5Stack Ultra-Wideband (UWB) Unit Indoor Positioning module 16GB and avoid assigning GD00 andDescription M5Stack Unit UWB is a DW1000 UWB module for indoor wireless ranging and position measurement. It uses the Ai Thinker BU01 module solution based on Decawave DW1000, integrates an STM32 controller and ranging algorithm, and exposes AT command control over a serial interface. As an indoor positioning module, it supports base station and tag operating modes. In a ranging setup, the base station calculates and outputs position information to
