Ai-Thinker BU01 DW1000 UWB Positioning Module

Description

Ai-Thinker BU01 DW1000 UWB Positioning Module The Ai-Thinker BU01 DW1000 UWB Positioning Module is a cutting-edge solution designed for high-precision indoor positioning and ranging, leveraging Ultra-Wideband (UWB) technology to deliver exceptional accuracy of up to 10 cm. This module is ideal for applications requiring precise location tracking, such as real-time location systems (RTLS), asset tracking, indoor navigation, and proximity detection. Powered by the Decawave DW1000 chip, a leading UWB transceiver, the BU01 integrates an on-board PCB antenna, RF circuits, power management, and clock circuits, providing a compact and efficient design for seamless integration into various IoT projects. Features: Simple integration without RF design. Using RTLS infrastructure to expand communication range. Super multipath fading has strong anti-interference ability. Support high label density. Compliant with IEEE 802.15.4-2011 UWB standard. Supports 3.5 GHz to 6.5 GHz operating frequency band. Programmable transmit power. Power 2.8 V to 3.6 V. Power consumption <1mA in sleep mode. Support two-way ranging and TDOA. Support SPI interface. Data rate: 110 kbps, 850 kbps, 6.8 Mbps.
