MaUWB ESP32-S3 Positioning System

Ultra-wideband (UWB) positioning system using ESP32-S3 and Makerfabs UWB modules for indoor positioning and warehouse mapping applications.

Features

ESP32-S3 based anchor and tag devices
Real-time distance measurement with <10cm accuracy
OLED display for status and measurements
Multiple tag support (up to 64 tags)
6.8Mbps communication rate
Complete AT command implementation
Position calculation with trilateration
Anchor auto-positioning system
Real-time positioning with USB data logging

Hardware: Makerfabs MaUWB ESP32-S3 UWB Module with SSD1306 OLED displays

Environments

anchor: Base station for positioning
tag: Mobile device for tracking (ID 1)
tag2: Mobile device for tracking (ID 2)
