Getting started with X-NUCLEO-53L1A1 long distance ranging ToF
sensor expansion board based on VL53L1X for STM32 Nucleo
Introduction
This document provides detailed hardware information on the X-NUCLEO-53L1A1
expansion board. This expansion board is compatible with the STM32 Nucleo family and the
Arduino™ electronic boards. It is designed around the VL53L1X ranging sensor and is
based on the ST patented FlightSense™ technology.
To allow the user to validate the VL53L1X in an environment as close as possible to its final
application, the X-NUCLEO-53L1A1 expansion board is delivered with a holder in which
three different height spacers of 0.25, 0.5, 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 VL53L1X sensor and the cover glass.
The X-NUCLEO-53L1A1 expansion board is delivered with two VL53L1X breakout boards.
