SparkFun Qwiic ToF Imager - VL53L5CX

The SparkFun Qwiic ToF Imager represents a massive leap forward in distance sensing. Built around the state-of-the-art VL53L5CX from STMicroelectronics, this board doesn't just measure the distance to a single point—it captures a "depth video" of the world in front of it. By integrating a SPAD array, physical infrared filters, and diffractive optical elements (DOE), this sensor provides a 64-pixel (8x8) grid of distance measurements, effectively giving your robot or project "vision" rather than just a simple proximity check.

Qwiic Convenience

To make integration easy, all communication is enacted exclusively via I²C through our handy Qwiic Connect System, so no soldering is required to connect it to your chosen microcontroller. However, we have still broken out 0.1”-spaced pins in case you prefer to use a standard breadboard.

Multizone Ranging & Algorithms

Unlike standard sensors that see a narrow beam, the VL53L5CX offers a wide 63° diagonal Field-of-View and complex processing capabilities:

• 64 Zones: The sensor reports distance for up to 64 zones simultaneously, enabling 3D room mapping, gesture recognition, and advanced obstacle detection.
• Long Range: Capable of measuring distances up to 4000mm (4 meters) across all zones at speeds up to 15Hz.
• Smart Detection: Thanks to ST's patented Histogram algorithms, the sensor can detect multiple objects within the Field-of-View and provides immunity to crosstalk from cover glass (beyond 60cm).

Controller Compatibility

This sensor is highly advanced, and with that power comes a specific requirement: it must load its firmware (~90KB) over the I²C bus every time it powers on. This means standard 8-bit microcontrollers like the Arduino Uno do not have enough flash memory to handle this sensor. To use this imager, you will need a more capable board with sufficient memory, such as the SparkFun Artemis, an ESP32-equipped board, or a Raspberry Pi RP2040/RP2350 board.
