P-NUCLEO-53L1A2 Data brief VL53L1 nucleo pack with X-NUCLEO-53L1A2 expansion board and STM32F401RE nucleo board Features X-NUCLEO-53L1A2 expansion board including the VL53L1 ToF (Time-of-Flight) ranging sensor with multi object detection and FoV (field of view) programming STM32F401RE nucleo board Two VL53L1 breakout boards 0.25, 0.5 and 1 mm spacers to simulate air gaps between ToF sensor and cover window Two different cover windows Equipped with an Arduino UNO R3 connector RoHS compliant The two VL53L1 breakout boards can be connected onto the X- NUCLEO-53L1A2 expansion board to integrate the VL53L1 into the customers application Full system SW (software) is supplied, including code examples and graphical user interface. All this can be downloaded on the product page on st.com. Description The P-NUCLEO-53L1A2 is a complete evaluation kit which allows anyone to learn, evaluate, and develop their application using the VL53L1 ToF, ranging sensor with multi object detection and FoV programming. The VL53L1 is a state-of-the-art, ToF, laser-ranging, miniature sensor enhancing STMicroelectronic s FlightSense product family. Housed in a miniature and reflowable package, it integrates a SPAD (single photon avalanche diode) array, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover windows. The STM32 nucleo board and NUCLEO-F401RE provide an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 Order code Description microcontroller, choosing from the various combinations of performance, power consumption, and features.

It integrates: a 2.8 V regulator to supply the VL53L1 on the expansion board and two breakout boards two level shifters to adapt the I/O level to the main board of the microcontroller the necessary connectivity for the application The NUCLEO-F401RE board has to be programmed to control the X-NUCLEO-53L1A2 expansion board. The required software suite is available on the product page on st.com and is composed of the X-CUBE-53L1A2. The X-NUCLEO-53L1A2 expansion board and the NUCLEO-F401RE board are connected through four Arduino compatible connectors: CN5, CN6, CN8, and CN9 (see the figure and tables below). The Arduino connectors on the NUCLEO-F401RE board support the Arduino Uno Revision 3. Figure 1. Arduino connector layout on the X-NUCLEO-53L1A2 expansion board DB4261 - Rev 1 page 2/9
