Overview
The Arduino Stella is a purpose-built Ultra-Wideband (UWB) development board that brings precision indoor positioning to the Arduino ecosystem. Powered by the Nordic nRF52840 ARM Cortex-M4F at 64MHz with BLE 5.0, it integrates the Truesense DCU040 UWB module for centimeter-accurate ranging and location tracking — far more precise than WiFi or Bluetooth positioning.
UWB technology enables use cases that were previously impractical with standard wireless protocols: real-time asset tracking in warehouses, follow-me autonomous vehicles, hands-free access control, precise indoor navigation, and secure device interactions. The board supports Apple Nearby Interaction, Android UWB Jetpack, and NXP Trimension frameworks for seamless smartphone integration.
The Stella is designed for logistics, healthcare, smart buildings, and industrial automation applications where knowing exact device position matters. It connects to the Arduino ecosystem for easy prototyping while delivering industrial-grade UWB performance.
