VL53L5CX

X-NUCLEO-53L5A1 Hardware Description

•The X-NUCLEO-53L5A1 is a Time-of-Flight 8x8

multizone ranging sensor with wide field of view

and development board designed around the

VL53L5CX sensor based on ST FlightSense™

patented technology

•The VL53L5CX communicates with the STM32

Nucleo developer board host microcontroller

through an I2C link available on the Arduino UNO

R3 connector.

Breakout boards

VL53L5CX-SATEL breakout boards can be

purchased separately

•X-NUCLEO-53L5A1 expansion board

•VL53L5CX devices in custom applications can be integrated with

expansion board, or external VL53L5CX breakout.

•The breakout boards are delivered separately.

•X-NUCLEO-53L5A1 is also available as a NUCLEO Pack

(P-NUCLEO-53L5A1)

•The X-NUCLEO-53L5A1 expansion board can also be ordered

on www.st.com as part of a NUCLEO Pack with expansion board

and STM32 NUCLEO board.

•Order code: P-NUCLEO-53L5A1:

Hardware Overview (2/2)

•The X-CUBE-TOF1 software package is a

STM32Cube expansion for the expansion boards

of the Time-of-Flight product family (including the

X-NUCLEO-53L5A1) for STM32. The source

code is based on STM32Cube to ease portability

and code sharing across different STM32 MCU

families. A sample implementation is available for

the STM32 Nucleo ranging sensor expansion

board (X-NUCLEO-53L5A1) plugged on top of

an STM32 Nucleo development board

(NUCLEO-F401RE or NUCLEO-L476RG).

SW prerequisites

Setup & Demo Examples

NUCLEO Kit driver installation

1. Connect the Nucleo pack to the PC through USB

•Wait for the board to be recognized;

the drivers are installed automatically)

•If Windows cannot install automatically the

STLINK driver, please follow step 2

2. Install the PC USB port driver to detect the Nucleo board

•Called STSW-LINK009, downloaded from www.st.com

• Unzip, extract the docs, and install “stlink_winusb_install.bat”

=> VL53L5CX nucleo kit is ready for GUI installation
