SB040192025 – DISTANCE SENSOR SCHEMATIC BLOCK

This schematic block features the VL53L5CXV0GC/1, a high-performance Time‑of‑Flight (ToF) ranging sensor from STMicroelectronics. It offers multizone distance measurements (up to 8×8 zones) across a wide field of view, enabling spatial mapping, gesture detection, and object tracking in a compact form factor. The sensor’s direct ToF architecture allows consistent distance estimation regardless of target reflectance or color.

Coming in a small optical LGA package, this breakout-style module exposes I²C lines, power rails, and interrupt capability for threshold-based wake-up. It supports autonomous low‑power mode, allowing the MCU to sleep until relevant motion or range changes are detected.

Key Features:

• Multizone ranging: up to 8×8 real-time zones
• Wide field of view: around 63° diagonal
• Distance measurement up to 400 cm (each zone)
• Frame rate: up to 60 Hz
• Multitarget detection: can detect multiple objects per zone
• Motion indicator per zone: detects movement within the field
• Power: supports flexible voltage options (e.g. 2.8 V or 3.3 V)
• Interface: I²C for control and data output
• Low‑power autonomous mode with interrupt-driven wake-up
• 940 nm VCSEL light source and SPAD array receiver
• Built‑in algorithms to handle cover glass crosstalk and ambient light

Typical Applications:

• 3D room mapping and scene understanding
• Obstacle detection for robots and drones
• Gesture recognition and motion-based interfaces
• Smart building presence detection and lighting control
• Liquid level sensing and filling systems
• Augmented / virtual reality (depth assist)
• Laser-assisted autofocus in imaging systems

By integrating this Quickboards block, engineers can rapidly prototype a depth‑sensing or spatial‑awareness system, reduce firmware complexity with built-in algorithms, and leverage a powerful, compact ToF sensor that’s production-ready.
