Introduction

The

development board equipped with the Arduino R3

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.
