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.

•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).

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”
