Ai-Thinker BU01 UWB Indoor Positioning Module | DecaWave DW1000 Ultra-Wideband Wireless Module for High-Precision Indoor Localization and TDOA Systems
The Ai-Thinker BU01 is a high-accuracy ultra-wideband (UWB) wireless module built around the DecaWave DW1000 chipset — the industry-standard UWB silicon for indoor positioning, ranging, and asset tracking applications. The BU01 integrates the RF circuitry, clock management, power management, and PCB antenna in a single compact SMD module, ready for SMT integration into custom positioning systems.
Operates in the 3.5–6.8 GHz UWB frequency band per IEEE 802.15.4-2011, supporting both bidirectional ranging and TDOA (Time Difference Of Arrival) positioning systems down to 10 cm accuracy. Up to 6.8 Mbps data rate delivers real-time location updates suitable for high-throughput indoor tracking. Operates at 3.3V with LDO power mode for stable performance across the -40°C to +85°C industrial temperature range — production-grade for factory floor, warehouse, and hospital deployments.
Typical Applications
- Indoor positioning and tracking systems — asset tags, personnel safety, real-time location services (RTLS).
- Smart factories and industrial automation — robot fleet management, tool tracking, production line monitoring.
- Warehouse logistics and asset management — pallet tracking, forklift positioning, picking optimisation.
- Parking management and tunnel traffic monitoring — vehicle positioning in GPS-denied environments.
- Hospitals, exhibition halls, smart buildings — patient flow, visitor tracking, indoor wayfinding.

FAQ — BU01 UWB Module
Q: What's the difference between UWB and traditional wireless tracking (BLE / WiFi RTLS)?
A: UWB achieves 10 cm accuracy by measuring time-of-flight of nanosecond-wide pulses across the 3.5-6.8 GHz band. BLE / WiFi RTLS rely on RSSI (signal strength) which is sensitive to multipath and reflections — typical accuracy is 1-3 meters in indoor environments. UWB is the right choice when sub-meter accuracy matters.
Q: How many anchor nodes do I need to deploy?
A: TDOA positioning requires a minimum of 4 anchor nodes for 3D positioning (3 for 2D) within the coverage area. Anchor spacing depends on environment — typically 10-30m for clear line-of-sight, less in cluttered industrial environments.
Q: Is the DW1000 chipset still in production?
A: Yes — the DW1000 remains the most-deployed UWB silicon globally despite the introduction of newer DW3000 / DW3210. The BU01 module continues to be supported and stocked for retrofit and new designs.
Q: Bulk pricing for production deployments?
A: Yes — email contact@lys-sz.com with your quantity and use case for tier pricing.
