Getting started with the X-NUCLEO-53L7A1 expansion board for STM32 Nucleo
Introduction
The
X-NUCLEO-53L7A1
is an expansion board for any
connectors. It provides a complete evaluation kit that allows you to learn, evaluate, and develop applications using the
VL53L7CX
Time-of-Flight 8x8 multizone ranging sensor with 90° FoV.
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
VL53L7CX
applications with Bluetooth or Wi-Fi interfaces.
