The P-NUCLEO-53L4A1 is a complete evaluation kit that allows you to learn, evaluate, and develop applications using the VL53L4CD Time-of-Flight high-accuracy proximity sensor. Specifically designed for proximity and short-range measurements, the VL53L4CD provides very accurate distance measurements from 1 mm up to 1300 mm. A new generation laser emitter with 18° FoV improves the performance under the ambient light, with a ranging speed of up to 100 Hz. With a very low-power consumption, thanks to an autonomous mode with a programmable distance threshold, the VL53L4CD is ideal for use in battery-powered devices. Its fully embedded on-chip processing helps to reduce design complexity as well as BOM cost, since less powerful and less expensive microcontrollers can be used. Like all Time-of-Flight (ToF) sensors based on ST FlightSense technology, the VL53L4CD records an absolute distance measurement, regardless of the target color and reflectance. The NUCLEO-F401RE STM32 Nucleo development board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller, choosing from the various combinations of performance, power consumption, and features.
