VL53L8CX
X-NUCLEO-53L8A1 Hardware Description
•The X-NUCLEO-53L8A1 is low-power high-
performance 8x8 multizone Time-of-Flight sensor
and development board designed around the
VL53L8CX sensor based on ST FlightSense™
patented technology
•The VL53L8CX communicates with the STM32
Nucleo developer board host microcontroller
through an I2C or SPI 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-53L8A1)
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-53L8A1) plugged on top
of an STM32 Nucleo development board (NUCLEO-
F401RE or NUCLEO-L476RG).

Setup & Demo Examples
NUCLEO Kit driver installation
1. Connect the P-NUCLEO 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
•Download STSW-LINK009 from www.st.com
• Unzip and double click on “stlink_winusb_install.bat” to install the driver
