Getting started with X-NUCLEO-53L5A1 Time-of-Flight 8x8 multi-zone ranging
sensor with wide FoV based on the VL53L5CX for STM32 Nucleo
Introduction
This document provides detailed hardware information on the X-NUCLEO-53L5A1 expansion board. This expansion board is
compatible with the STM32 Nucleo family and the Arduino™ electronic boards. It is designed around the VL53L5CX multi-zone
ranging sensor and is based on the ST patented FlightSense technology.
To allow the user to validate the VL53L5CX in an environment as close as possible to its final application, the
X‑NUCLEO-53L5A1 expansion board is delivered with a holder in which three different height spacers of 0.25 mm, 0.5 mm, and
1 mm can be fitted with the cover glass above the spacer. The height spacers are used to simulate different air gap distances
between the VL53L5CX sensor and the cover glass.
