X-NUCLEO-53L3A2 Data brief Time-of-Flight ranging sensor with multi target detection expansion board based on VL53L3CX for STM32 Nucleo Features VL53L3CX Time-of-Flight (ToF) ranging sensor with multi target detection Accurate absolute ranging distance, independent of the reflectance of the target 0.25, 0.5, and 1 mm spacers to simulate air gaps Two different cover windows Two VL53L3CX breakout boards Compatible with STM32 Nucleo board family Equipped with Arduino UNO R3 connector RoHS compliant Full system software (SW) supplied, including code examples and graphical user interface. All this can be downloaded from the VL53L3CX product page on st.com. Description The X-NUCLEO-53L3A2 is an expansion board for the NUCLEO-F401RE development board. It provides a complete evaluation kit allowing anyone to learn, evaluate, and develop their applications using the VL53L3CX, ranging sensor with multi target detection.. The X-NUCLEO-53L3A2 expansion board is delivered with a cover glass holder in which three different spacers of 0.25, 0.5, and 1 mm height can be fitted below the cover glass to simulate various air gaps. Two VL53L3CX breakout boards can be connected using two 10-pin connectors. The X-NUCLEO-53L3A2 expansion board is compatible with the STM32 nucleo board family, and with the Arduino UNO R3 connector layout. Several ST expansion boards can be superposed through the Arduino connectors which allows, for example, the development of VL53L3CX applications with Bluetooth or Wi-Fi interfaces.
