BU04 dual-antenna UWB positioning module based on DW3000 and STM32F103, supporting TWR, TDOA and PDOA with up to 10 cm accuracy.

The Ai-Thinker BU03 UWB Positioning Module is a compact high-precision wireless module designed for indoor positioning, ranging, and RTLS applications. With an integrated ceramic antenna, it supports TWR, TDOA, and PDOA, UWB data rates up to 6.8 Mbps, and positioning accuracy of up to 10 cm under suitable conditions. Featuring SPI, 9 GPIOs, AES-256 encryption, and low-power operation, it is ideal for warehouses, hospitals, robotics, mine-shaft tracking, and smart IoT systems.

The Ai-Thinker BU03-Kit UWB Development Board combines a BU03 UWB module with an STM32F103C8T6 MCU for precise positioning and ranging applications. It supports TWR, TDOA, and PDOA, data rates up to 6.8 Mbps, and positioning accuracy of up to 10 cm under suitable conditions. With an integrated antenna, SPI, 9 GPIOs, AES-256 encryption, and low-power operation, it is ideal for RTLS, IoT, robotics, wearables, and indoor positioning projects.

The BU01 UWB Wireless Positioning Module is a compact 3.5GHz–6.5GHz Ultra-Wideband module designed for accurate indoor positioning, ranging, RTLS, robotics, and IoT applications. It supports TWR and TDOA positioning, SPI communication, programmable transmit power, and data rates up to 6.8Mbps. With 2.8V–3.6V operation and less than 1mA sleep current, it is ideal for compact, low-power wireless tracking and positioning systems.
