P-NUCLEO-53L1A1 VL53L1X nucleo pack with X-NUCLEO-53L1A1 expansion board and STM32F401RE nucleo board Data brief Description The P-NUCLEO-53L1A1 is a complete evaluation kit allowing anyone to learn, evaluate, and develop their application using the VL53L1X ToF, long-distance ranging sensor technology. The VL53L1X is the latest product based on STs TM patented FlightSense technology. This is a ground-breaking technology allowing absolute long-distance distance to be measured independently of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from an object (which is significantly influenced by color and surface), the VL53L1X precisely measures the time the light Features takes to travel to the nearest object and reflect VL53L1X Time-of-Flight (ToF), long-distance back to the sensor (Time-of-Flight). ranging sensor expansion board (X-NUCLEO- The STM32 nucleo board, NUCLEO-F401RE, 53L1A1) provides an affordable and flexible way for users STM32F401RE nucleo board to try out new ideas and build prototypes with any STM32 microcontroller, choosing from the various Two VL53L1X breakout boards combinations of performance, power 0.25, 0.5 and 1 mm height spacers to simulate consumption, and features. air gaps Two different cover windows Equipped with an Arduino UNO R3 connector RoHS compliant The two VL53L1X breakout boards can be connected onto the X-NUCLEO-53L1A1 expansion board to integrate the VL53L1X into the customers application Full system SW is supplied, including code examples and graphical user interface.

It integrates: A 2.8 V regulator to supply the VL53L1X 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-53L1A1 expansion board. The required software suite is available on www.st.com/VL53L1X and is composed of the STSW-LINK009, STSW-LINK7, and X-CUBE-53L1A1. The X-NUCLEO-53L1A1 expansion board and the NUCLEO-F401RE board are connected through four Arduino compatible connectors: CN5, CN6, CN8, and CN9. They are shown in Figure 3 and described in Table 1 and Table 2. The Arduino connectors on the NUCLEO-F401RE board support Arduino Uno revision 3. Figure 1.
