How to use the VL6180 proximity sensor X-NUCLEO-6180A1 expansion board
Introduction
This user manual provides detailed hardware information on the X-NUCLEO-6180A1 expansion board (see figure below). This
board is designed around the VL6180 proximity sensor and it is compatible with the STM32 Nucleo and Arduino Uno boards.
The document provides an introduction to the proximity sensing capabilities of the VL6180 module which is based on ST's
patented Time-of-Flight (ToF) technology. Several ST expansion boards can be superposed through the Arduino connectors,
which allow development of VL6180 applications with Bluetooth or WiFi interfaces.

X-NUCLEO-6180A1 expansion board with level shifters The level shifters are used only to provide adequate voltage for the I/O’s and I2C bus which allows a 5 V Arduino board to be connected without hardware modifications. In a final product, depending on the power management tree, the level shifters could be omitted.
