Introduction
This document provides detailed hardware information on the X-NUCLEO-53L1A2 expansion board. This expansion board is
compatible with the STM32 Nucleo family and the Arduino™ electronic boards. It is designed around the VL53L1 long distance
ranging sensor with multi target detection, and is based on the ST patented FlightSense technology.
To allow the user to validate the VL53L1 in an environment as close as possible to its final application, the X-NUCLEO-53L1A2
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 VL53L1
sensor and the cover glass.
The X-NUCLEO-53L1A2 expansion board is delivered with two VL53L1 breakout boards.
