UWB With Arduino: Unlocking Precise Positioning for IoT
summary
Ultra wideband is shown implemented on Arduino hardware: an Arduino Stella and Portenta UWB shield pair plus libraries and open‑source iOS/Android reference apps. Claims include ranging precision of ±5 cm and 3° and three modes: two‑way ranging (single and double sided), TDOA for scalable anchor-based tracking, and downlink DOA for low‑latency on‑device positioning. A CR2032 tag example runs 3 months at 5 Hz; a realtime TDOA system and firmware examples are promised open source and usable now.
