Overview

LEDswarm is a Rust-based firmware that turns Makerfabs ESP32 UWB DW3000 boards into a self-organizing mesh network of LED controllers. Each node uses UWB ranging for decimeter-level positioning and coordinates lighting effects based on spatial relationships.

Features

  • UWB mesh networking via DW3000 for automatic device discovery and formation
  • Decimeter-level ranging between nodes for position-aware lighting
  • Addressable LED support for NeoPixel/SK6812 RGBW strips
  • Wi-Fi hotspot capability on master nodes
  • Status LED patterns indicating Discovery, Connecting, Client, and Server modes
  • Game controller functionality for interactive applications

Operation Modes

  • Client mode: Joins an existing network session
  • Server/Master mode: Creates a new network session with Wi-Fi hotspot

Technology Stack

  • Rust with ESP-IDF framework
  • cargo-espflash for deployment
  • Currently only supports Makerfabs DW3000 board (more boards planned)
