1 Overview
The X-NUCLEO-53L1A2expansion board features the VL53L1 ranging sensor, 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-53L1A2expansion board is delivered with:
•
Three spacers of 0.25, 0.5, 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’sfinal
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-pinconnectors to enable the customerto connect the two breakout boards onto
the X-NUCLEO-53L1A2expansion 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.
