Gravity: 8x8 Matrix ToF 3D Distance Sensor I2C & UART 3.5m Range, 60 FOV

The Gravity 8×8 Matrix ToF 3D Distance Sensor is a compact and intelligent depth-sensing module designed to deliver reliable three-dimensional distance data for advanced sensing applications. Powered by onboard firmware running on the RP2040 microcontroller, it provides real-time depth information across an 8×8 grid of 64 pixels within a wide 60° field of view, with a sensing range of up to 3.5 metres. Positioned between basic distance sensors and complex depth cameras, this module offers an optimal balance of performance, size, and power efficiency. With plug-and-play Gravity interface support and compatibility with popular platforms such as Arduino, micro:bit, ESP32, Raspberry Pi, and LattePanda, it enables rapid development of smart robotics, gesture recognition systems, and interactive automation projects.

3D Depth Perception at the Perfect Balance Point

This 3D robot obstacle avoidance sensor fills the gap between basic ultrasonic sensors and expensive AI depth cameras. Instead of perceiving a single point, it creates a 64-pixel depth map with context—the obstruction, the open path, the edge of a table. This allows for seamless, intelligent navigation without the complexity and processing demands of modern cameras. With reasonable pricing and ultra-low power consumption, it provides the "just right" level of 3D vision for a wide range of creative tasks.

Unmatched Compatibility for Maker Projects

This Matrix ToF proximity sensor was built for the way makers work, designed to connect to virtually anything in the workshop.

• Supported Platforms: Arduino, micro:bit, ESP32, Raspberry Pi, LattePanda, and UNIHIKER K10.
• Supported Programming Methods: Libraries and tutorials are available for the Arduino IDE as well as graphical editors like Mind+ and MakeCode.
• Connections: Gravity-I2C, UART, and USB-C are supported.
• Cascading Support: With four switchable I2C addresses, you may daisy-chain up to four sensors together for a huge field of view.

Expandable Platform for Advanced Development

In addition to plug-and-play functionality, the 64-Pixel Matrix ToF Vision Sensor can be used as a versatile development platform. Its integrated RP2040 processor enables developers to load custom firmware or run lightweight machine learning models (TinyML), allowing them to recognize specific gestures, monitor movement patterns, and add new capabilities straight to the sensor itself. With open-source schematics and extensive documentation, the module may be customized for advanced robotics, IoT, and AI-driven applications, providing far more than just a fixed-function sensor.
