Positioning requires at least 2 modules to work - we recommend 4 for full 3D positioning!

The BU-03 Kit from AI Thinker brings localised positioning technology within reach for makers and hobbyists. Originally only accessible for industrial projects, this module provides precise distance measurements with an easy-to-use serial AT command interface, making it ideal for projects requiring accurate proximity or positioning, like robotics.

These measure distance between boards, so with enough of them and some math (that is handled on the devices), you can infer an XYZ position.

This compact module operates similarly to a GPS device but with a much shorter range (up to 25 metres line-of-sight). By deploying multiple base stations, two for point-to-point distance measurement, three for 2D positioning, or four for 3D positioning - along with the 'tag' that you are tracking (All are this same unit), you can achieve increasingly precise spatial awareness for your projects.

Our own guide coming soon!

Specifications

Power Supply: 5V (peak current 500mA)
Logic Level: 3.3V
Operating Range: Up to 40 metres (line of sight)
Positioning Accuracy: Typically 10 centimetres
Onboard hardware: DW3220 and STM32F103
Interface: Serial output using AT commands

Like GPS - it is desirable to have more than the minimum amount of reference stations (3 for 3D tracking, one tag = 4 total), more stations increases the accuracy of the position measurement.

Compatibility

Microcontrollers and development boards with 3.3V logic level UART support
Serial communication interfaces supporting AT commands
Suitable for projects needing accurate proximity detection or indoor positioning
Can be integrated with custom STM32 or Arduino setups with appropriate level shifting
Works well in maker and prototyping environments, once exclusive to industrial applications
