X-NUCLEO-53L0A1 ranging and gesture detection sensor
expansion board based on VL53L0X for STM32 Nucleo
Introduction
This document provides detailed hardware information on X-NUCLEO-53L0A1 expansion
board.
The X-NUCLEO-53L0A1 expansion board is compatible with STM32 Nucleo family and
Arduino™ electronic boards.
This product is part of STMicroelectronics offering of expansion boards designed around the
VL53L0X ranging and gesture recognition sensor, based on ST patented FlightSense™
technology.
To allow the user to validate the VL53L0X in an environment as close as possible to its final
application, the X-NUCLEO-53L0A1 expansion board is delivered with a holder in which 3
different height spacers of 0.25, 0.5 and 1mm, used to simulate the air gap, can be fitted,
with the cover glass above the spacer.
To allow the user to quickly access the gesture recognition demonstration, the
X-NUCLEO-53L0A1 expansion board is delivered with two VL53L0X satellites.
Demonstration software, available on www.st.com/VL53L0X, is included in the
X-CUBE-53L0A1.

1 Overview
The X-NUCLEO-53L0A1 expansion board features the VL53L0X ranging and gesture
recognition sensor, based on ST’s FlightSense™, Time-of-Flight technology.
It is compatible with the STM32 Nucleo board family, and with the Arduino UNO R3
connector layout.
Several ST expansion boards can be superposed through the Arduino connectors, which
allows, for example, to develop VL53L0X applications with Bluetooth or Wi-Fi interface.
The X-NUCLEO-53L0A1 expansion board is delivered with:
•Three spacers of 0.25, 0.5 and 1 mm height, used to simulate different airgap between
the VL53L0X and the cover glass
•A cover glass to simulate the integration of the VL53L0X into the customer’s final
product.
•Two VL53L0X satellites, which can be plugged onto the X-NUCLEO-53L0A1 expansion
board or connected through flying wires to the X-NUCLEO-53L0A1 expansion board.
•Two 10 pin connectors to enable customer to connect the two satellites onto the
X-NUCLEO-53L0A1 expansion board.
Note: The VL53L0X is delivered with a liner, in order to prevent potential foreign material to
penetrate inside the modules holes during assembly process. It must be removed at the
latest possible step during final assembly, and anyway before module calibration.

It is fundamental to program a micro-controller to control the VL53L0X through the I2C bus
and drive the 4-digit display on board. Application software and examples of C-ANSI source
code are available on www.st.com/VL53L0X.
The X-NUCLEO-53L0A1 expansion board and STM32 Nucleo are connected through
Arduino compatible connectors CN5, CN6, CN8 and CN9 as shown in Figure 3 and
described in Table 3 and Table 4.
The Arduino connectors on STM32 Nucleo board support Arduino Uno Revision 3.

3.3 Solder drop configurations
Solder drops allow the following configurations for X-NUCLEO-53L0A1 boards:
•In case the developer wants to do an application with several expansion boards
superposed and:
– there is a conflict on microcontroller port allocation, the GPIO1 can be outputted
on CN8/A4 (U17 fitted) of the Arduino connector. The default configuration is
GPIO1 is outputted on CN8/A2 (U14 fitted) of the Arduino connector.
– there is a conflict on I2C addresses, the addresses of the STMPE1600 can be
modified.(default addresses A2,A1,A0: 000 and 001).
•In case the developer wants to connect satellites (see Figure 5):
– the VL53L0X interrupt of the left satellite board can be outputted on CN5/D9 (U10
fitted) or CN5/D8 (U11 fitted) of the Arduino connector. By default U10 and U11
are not fitted.
– the VL53L0X interrupt of the right satellite board can be outputted on CN9/D4
(U15 fitted) or CN9/D2 (U18 fitted) of the Arduino connector. By default U15 and
U18 are not fitted.
– the VL53L0X interrupts of left and right satellite boards, GPIO1_L and GPIO1_R,
can be shared with the VL53L0X interrupt on the main board, GPIO1, by fitting U7
and U8 solder drops. By default U7 and U8 are not fitted.

4 VL53L0X satellite
The VL53L0X satellites are supplied at 2.8V by the regulator present on the
X-NUCLEO-53L0A1 expansion board.
Figure 7. VL53L0X satellite schematic
The VL53L0X satellites can be directly plugged onto the X-NUCLEO-53L0A1 expansion
board through the two 10 pin connectors or connected to the board through flying leads.
When connected through flying leads, developers should break off the mini PCB from the
satellite board, and use only the “VL53L0X mini PCB” which benefits from a smaller form
factor for an easier integration into customers devices.

5 Safety
5.1 Electrostatic precaution
Figure 9. Electrostatic logo
You should exercise electrostatic precautions, including using ground straps when using the
X-NUCLEO-53L0A1 expansion board. Failure to prevent electrostatic discharge could
damage the device.
5.2 Laser considerations
The VL53L0X contains a laser emitter and corresponding drive circuitry. The laser output is
designed to remain within Class 1 laser safety limits under all reasonably foreseeable
conditions including single faults in compliance with IEC 60825-1:2014 (third edition). The
laser output will remain within Class 1 limits as long as the STMicroelectronics
recommended device settings are used and the operating conditions specified in the
datasheet are respected. The laser output power must not be increased by any means and
no optics should be used with the intention of focusing the laser beam.
