The M5Stack UWB Unit Indoor Positioning Module provides precise indoor wireless positioning with up to 10cm accuracy, making it ideal for real-time tracking, ranging, and smart location-aware applications.

The M5Stack UWB Unit Indoor Positioning module is a wireless communication unit equipped with indoor positioning technology.

The design adopts the Ai-Thinker BU01 module solution (an ultra-wideband (UWB) transceiver module based on Decawave’s DW1000).

It features a built-in STM32 and integrated ranging algorithm, achieving a positioning accuracy of up to 10 cm, and supports AT command control. When applied to indoor wireless ranging, it operates in base station and tag modes (the base station calculates and outputs position information to the tag).

Features

• Positioning accuracy: 10 cm
• Built-in STM32 with integrated ranging algorithm
• AT command control
• Serial communication (baud rate: 115200)
• Easy integration, no RF design required
• Complies with IEEE 802.15.4-2011 UWB standard
• Supports two-way ranging and TDOA
• Development platforms: Arduino, UIFlow (Blockly, Python)
• 2 x LEGO-compatible holes

Specifications

Important Information

• The firmware currently installed on this unit only supports the transmission of ranging information and does not support custom information transmission. When in use, it supports the configuration of up to 4 base station devices (using different IDs), and only a single tag device is allowed to operate at any given time.
