STMicroelectronics P-NUCLEO-53L4A2-

Overview

P-NUCLEO-53L4A2 from STMicroelectronics is a complete evaluation kit comprising the VL53L4CX Time-of-Flight sensor expansion board (X-NUCLEO-53L4A2) and the NUCLEO-F401RE STM32 development board, enabling rapid prototyping of long-range, multi-target distance sensing up to 6 m with 18° FoV, Class 1 laser safety compliance, and cover-glass crosstalk immunity beyond 80 cm.

For engineers reviewing the P-NUCLEO-53L4A2 datasheet, P-NUCLEO-53L4A2 pinout, P-NUCLEO-53L4A2 application, or P-NUCLEO-53L4A2 equivalent, this kit delivers production-ready firmware, GUI-based configuration (STSW-IMG030), Arduino UNO R3-compatible connectivity, and validated hardware integration for embedded ToF system development in AR/VR, drones, and wearable proximity sensing.

Technical Context

The kit integrates two tightly coupled subsystems: the X-NUCLEO-53L4A2 hosts the VL53L4CX sensor with on-board 3.3 V regulation, I²C interface, and laser driver circuitry compliant with IEC 60825-1:2014 Class 1 limits; the NUCLEO-F401RE provides an ARM Cortex-M4 MCU running at 84 MHz, supporting real-time sensor control and histogram data processing via ST's FlightSense firmware stack.

Hardware interconnection uses four Arduino Uno R3 headers (CN5, CN6, CN8, CN9) for GPIO, I²C, power, and reset signaling - no external level-shifting required. The included SATEL-VL53L4CX breakout boards enable remote sensor placement while maintaining full STSW-IMG030 GUI compatibility and smudge-compensated short-range operation below 80 cm.

FAQ

Does P-NUCLEO-53L4A2 support multiple target detection?

Yes. The VL53L4CX sensor on the X-NUCLEO-53L4A2 uses ST's histogram algorithm to resolve up to three distinct targets within its 18° field of view, delivering individual distance and confidence metrics per object - validated in STSW-IMG030 GUI and supported by onboard STM32F401RE processing.

Can the VL53L4CX operate through cover glass?

Yes. The sensor implements dynamic smudge compensation for targets below 80 cm and cover-glass crosstalk immunity beyond 80 cm using patented optical calibration and histogram post-processing - both functions are active by default in the provided firmware and GUI.

Is external power required for the X-NUCLEO-53L4A2 board?

No. The X-NUCLEO-53L4A2 integrates a dedicated 3.3 V regulator powered directly from the NUCLEO-F401RE board via Arduino connectors, eliminating need for external supplies or voltage translation when used as intended in the kit.

What software tools are included with P-NUCLEO-53L4A2?

The kit ships with STSW-IMG030 - a Windows-based GUI offering real-time distance plotting, histogram visualization, multi-target configuration, and register-level access - plus full C source code examples for STM32CubeIDE, enabling custom firmware development without licensing restrictions.
