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

Unit UWB is a wireless communication unit equipped with indoor positioning technology. The design adopts the Ai-Thinker BU01 module solution (an ultra-wideband (UWB) transceiver module based on Decawave's DW1000). It features a built-in STM32 and integrated ranging algorithm, achieving a positioning accuracy of up to 10 cm, and supports AT command control. When applied to indoor wireless ranging, it operates in base station and tag modes (the base station calculates and outputs position… (M5Stack U100)
