The expansion board is delivered with a cover glass holder in which you can fit three different spacers of 0.25, 0.5, and 1 mm height below the cover glass to simulate various air gaps. A small oval cover glass fitting the sensor is included. Several ST expansion boards can be stacked through the Arduino connectors, which allow, for example, the development of VL53L4CX applications with Bluetooth or Wi-Fi interfaces.
Getting started Getting started Safety considerations 1.1.1 Electrostatic precautions Warning: Take electrostatic precautions, including ground straps, when using the X-NUCLEO-53L4A2 expansion board. Failure to prevent electrostatic discharge could damage the device. Figure 2. Electrostatic logo 1.1.2 Laser safety considerations VL53L4CX contains a laser emitter and the corresponding drive circuitry.

UM2976 Using the expansion board Using the expansion board X-NUCLEO-53L4A2 expansion board allows the user to test the VL53L4CX sensor functionality, to program it and to understand how to develop an application using this sensor. X-NUCLEO-53L4A2 integrates: • VL53L4CX sensor;...
UM2976 Breakout boards Breakout boards X-NUCLEO-53L4A2 package does not include the VL53L4CX breakout boards. You can purchase them in a pack of two PCBs as SATEL-VL53L4CX. X-NUCLEO-53L4A2 supplies the VL53L4CX breakout boards at 3.3 V (see Figure For mechanical integration purposes, it could be interesting to use the mini PCB by breaking the...
UM2976 Graphical user interface (GUI) and programming example for the X-NUCLEO-53L4A2 Graphical user interface (GUI) and programming example for the X-NUCLEO-53L4A2 To evaluate the VL53L4CX device performance, use the related GUI or the X-CUBE-TOF1. X-NUCLEO-53L4A2 expansion board requires the NUCLEO-F401RE development board to use the GUI or run the ranging examples included in the X-CUBE-TOF1.
