Overview

The X-NUCLEO-53L7A1 is an expansion board for STM32 Nucleo development kits featuring the VL53L7CX multizone Time-of-Flight (ToF) sensor. It enables high-speed 3D distance sensing with an 8x8 multizone grid and a wide 90-degree field of view for advanced spatial awareness. The board is designed to interface via I2C and includes a divisible design for remote sensor placement.

Why Choose This Part

This board provides a wide 90-degree field of view, significantly larger than standard ToF sensors, allowing for better peripheral detection. Its divisible design allows engineers to snap off the sensor satellite for mounting in tight spaces while maintaining electrical connectivity to the Nucleo base.

Applications

Robotic Obstacle Avoidance
Utilizing the 8x8 multizone grid to detect and bypass objects in the path of mobile robots.
Gesture Recognition
Implementing touchless control interfaces by tracking hand movements in 3D space.
Room Occupancy Monitoring
Mapping person movement and counting individuals within a defined zone for smart building automation.
Drone Landing Assistance
Providing high-speed downward-facing ranging for precision hovering and landing maneuvers.

Getting Started

Plug the expansion board into an STM32 Nucleo-64 or Nucleo-144 board using the Arduino Uno R3 connectors. Use the X-CUBE-TOF1 software expansion pack for STM32Cube to access driver libraries and example code for multizone ranging. Communication is handled via the I2C bus with support for temperature compensation from -40C to 85C.
