P-NUCLEO-53L0A1

P-NUCLEO-53L0A1 VL53L0X Nucleo pack with ranging, gesture detection sensor expansion board and STM32F401RE Data brief • Full system SW supplied, download from www.st.com/VL53L0X in the folder “Design resources”. Description The P-NUCLEO-53L0A1 is an evaluation pack that provides an introduction to the ranging and gesture detection features of the VL53L0X sensor, combined with the powerful STM32F401RE microcontroller. Features • VL53L0X ranging and gesture detection expansion board (X-NUCLEO-53L0A1). – 4-digit display, displaying the distance of a target from the ranging sensor – Accurate absolute ranging distance, independent of the reflectance of the target. • NUCLEO-F401RE STM32 Nucleo board • Two VL53L0X satellites • 0.25, 0.5 and 1mm height spacers to simulate air gaps The VL53L0X is the latest product based on ST’s patented FlightSenseTM technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL53L0X precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight). The STM32 Nucleo board, NUCLEO-F401RE, provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. • Cover glass • Two 10 pin connectors for VL53L0X satellite boards • Equipped with Arduino UNO R3 connector. • RoHS compliant. • Basic gesture recognition application can be developed using one or two VL53L0X sensors. • Two VL53L0X satellite boards can be connected on the X-NUCLEO-53L0A1 expansion board in order to integrate the VL53L0X in customer’s application.

Ordering code Order code P-NUCLEO-53L0A1 Description X-NUCLEO-53L0A1 and NUCLEO-F401RE boards NUCLEO-F401RE board Information about NUCLEO-F401RE board can be found at http://www.st.com/stm32nucleo. X-NUCLEO-53L0A1 expansion board The board allows the user to test the VL53L0X functionality, to program it and to help understand how to develop an application using VL53L0X. It integrates: • a 4-Digit display to display the range value in cm. • a 2.8V regulator to supply the VL53L0X on the expansion board and on the two satellite boards. • two level shifters to adapt the I/O level to the micro controller main board. • the necessary connectivity for the application. It is required to program the NUCLEO-F401RE board in order to control the X-NUCLEO53L0A1 expansion board. For the NUCLEO-F401RE board, the required software suite is available on www.st.com, on the P-NUCLEO-53L0A1 page, and is composed of STSW-LINK009, STSW-LINK7 and X-CUBE-53L0A1. The X-NUCLEO-53L0A1 expansion board and the NUCLEO-F401RE board are connected through Arduino compatible connectors CN5, CN6, CN8 and CN9 as shown in Figure 1 and described in Table 2 and Table 3. The Arduino connectors on NUCLEO-F401RE board support Arduino Uno Revision 3. 2/8 DocID029188 Rev 1 P-NUCLEO-53L0A1 X-NUCLEO-53L0A1 expansion board Figure 1.

When connected through flying leads, developers should break off the mini PCB from the satellite board, and use only the “VL53L0X mini PCB” which benefits from a smaller form factor for easier integration into customers devices. Figure 2. Connections of VL53L0X satellite boards Laser consideration The VL53L0X contains a laser emitter and corresponding drive circuitry. The laser output is designed to remain within Class 1 laser safety limits under all reasonably foreseeable conditions including single faults in compliance with IEC 60825-1:2014 (third edition). The laser output will remain within Class 1 limits as long as the STMicroelectronics recommended device settings are used and the operating conditions specified in the datasheet are respected. The laser output power must not be increased by any means and no optics should be used with the intention of focusing the laser beam. Figure 3.
