Getting started with the X-NUCLEO-53L4A1 expansion board for STM32 Nucleo
Introduction
The
X-NUCLEO-53L4A1
is an expansion board for any
connectors. It provides a complete evaluation kit that allows you to learn, evaluate, and develop applications using the
VL53L4CD
Time-of-Flight high-accuracy proximity sensor.
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
VL53L4CD
applications with Bluetooth or Wi-Fi interfaces.
