X-NUCLEO-53L0A1
Ranging and gesture detection sensor expansion board based on
VL53L0X for STM32 Nucleo
Data brief
• Compatible with STM32 Nucleo board family.
• Equipped with ArduinoTM UNO R3 connector.
• RoHS compliant.
• Full system SW supplied, download from
www.st.com/VL53L0X.
Description
Features
• VL53L0X ranging and gesture detection sensor
module.
• Accurate absolute ranging distance,
independent of the reflectance of the target.
• 4-digit display, displaying the distance of a
target from the ranging sensor.
• Basic gesture recognition application can be
developed with a VL53L0X module.
The X-NUCLEO-53L0A1 expansion board
features the VL53L0X ranging and gesture
detection sensor, based on ST’s FlightSense™,
Time-of-Flight technology.
It is an evaluation board that provides an
introduction to the ranging and gesture detection
capabilities of the VL53L0X module.
To allow the user to validate the VL53L0X in an
environment as close as possible to its final
application, the X-NUCLEO-53L0A1expansion
board is delivered with a cover glass holder in
which 3 different spacers of 0.25, 0.5 and 1mm
height can be fitted below the cover glass in order
to simulate various air gaps.
Two VL53L0X satellites can be connected using
the two 10 pin connectors.
The expansion board 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.

Optional VL53L0X satellite board
Optional VL53L0X satellite board
The VL53L0X satellites can be directly plugged onto the VL53L0X 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.

X-NUCLEO-53L0A1
Laser consideration
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 Edition 3. 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.
