Overview
The X-NUCLEO-53L1A2 expansion board features the VL53L1 long distance ranging sensor with multi target
detection, based on ST's FlightSense, Time-of-Flight (ToF) technology.
It is compatible with the STM32 Nucleo development board family, and with the Arduino UNO R3 connector
layout.
Several ST expansion boards can be stacked through the Arduino connectors, which allows, for example, the
development of VL53L1 applications with Bluetooth or Wi-Fi interfaces.
The X-NUCLEO-53L1A2 expansion board is delivered with:
•
Three spacers of 0.25 mm, 0.5 mm, and 1 mm height, used to simulate different air gaps between the
VL53L1 and the cover glass.
•
Two cover windows to simulate the integration of the VL53L1 into the customer's final product.
•
Two VL53L1 breakout boards which can be plugged onto the X-NUCLEO-53L1A2 expansion board or
connected through flying wires to the X-NUCLEO-53L1A2 expansion board.
•
Two 10-pin connectors to enable the customer to connect the two breakout boards onto the X-
NUCLEO-53L1A2 expansion board.
Note:
The VL53L1 is delivered with a liner to prevent potential foreign material from penetrating inside the module
holes during the assembly process. This liner must be removed at the latest possible step during final assembly,
before module calibration.
