P-NUCLEO-6180X1
Proximity, gesture, ambient light sensor expansion board based on
VL6180X for STM32F401RE
Data brief
integrate the VL6180X in customer’s
application.
• Basic gesture recognition application can be
developed using the VL6180X sensor on the
expansion board and/or up to three sensors on
the satellite boards.
Description
The P-NUCLEO-6180X1 is an evaluation pack
that provides an introduction to the proximity,
ranging and light sensing capabilities of the
VL6180X sensor, combined with the powerful
STM32F401RE microcontroller.
Features
• 1x VL6180X (proximity, gesture and ambient
light sensing module) expansion board.
– Slider switch controlling 2 functions:
- Ranging measurement.
- Ambient light sensing, up to 100KLux.(a)
– 4-digit display, displaying either the
distance of a target from the proximity
sensor or the lux value from the ambient
light sensing (ALS).
– Excellent ranging accuracy, independent of
the reflectance of the target.
• 1x NUCLEO-F401RE board
• Power management access point
• Equipped with Arduino UNO R3 connector.
• RoHS compliant.
The VL6180X is the latest product based on ST’s
patented FlightSenseTM technology. This is a
ground-breaking technology allowing absolute
distance to be measured independent of target
reflectance. Instead of estimating the distance by
measuring the amount of light reflected back from
the object (which is significantly influenced by
color and surface), the VL6180X precisely
measures the time the light takes to travel to the
nearest object and reflect back to the sensor
(Time-of-Flight).
The STM32 Nucleo board, NUCLEO-F401RE,
provides an affordable and flexible way for users
to try out new ideas and build prototypes with any
STM32 microcontroller line, choosing from the
various combinations of performance, power
consumption and features.
• Full system SW supplied, download from
www.st.com/vl6180x in the folder “Design
resources”.
• 3x VL6180X satellite boards can be connected
on the VL6180X expansion board, in order to
a. VL6180X detects up to 100KLux but since the display
is 4 digits only, maximum displayed value is limited to
9999 Lux

VL6180X expansion board
The board allows the user to test the VL6180X functionality, to program it and to help
understanding how to develop an application using VL6180X. It integrates:
•
a 4-Digit display to render either the range value in mm or the ambient light value in
Lux.
•
a switch to select the value type to be displayed.
•
a 2.8V regulator to supply the VL6180X.
•
two level shifters to adapt the I/O level to the micro controller main board.
•
the necessary connectivity for the application.
It is required to program the NUCLEO-F401RE board in order to control the VL6180X
expansion board. For the NUCLEO-F401RE board, the required software suite is available
on www.st.com, on the P-NUCLEO-6180X1 page, and is composed of
STSW-LINK008, STSW-LINK7 and the X-CUBE-6180XA1.
The VL6180X expansion board and the NUCLEO-F401RE board are connected through
Arduino compatible connectors CN5, CN6, CN8 and CN9 as shown in Figure 1 and
described in Table 2 and Table 3.
The Arduino connectors on NUCLEO-F401RE board support Arduino Uno Revision 3.

are duplicated, but not used, this offers hardware connection flexibility in case of conflict on MCU interface
management when expansion board is used superposed with other expansion boards, in this case
remove 0 ohm resistor from interrupt used and connect 0 ohm resistor in place of “do not mount” one.

The VL6180X expansion board allows connecting up to 3x VL6180X satellite boards (see
Figure 2). This allows to develop applications controlling up to 4x VL6180X.
•
I2C bus is common with the VL6180X on-board: I2C bus,
•
each satellite can be connected through a dedicated connector to be soldered on the
expansion board and has its own:
–
interrupt (GPIO1-x) pin, routed from each satellite connector to the Arduino Uno
connectors.
–
reset (GPIO0-y) pin, routed from each satellite connector to the GPIO expander
device.

Laser consideration
Laser consideration
The VL6180X contains a laser emitter and corresponding drive circuitry. The laser output is
designed to remain within Class 1 laser safety limits under all reasonably foreseeable
conditions including single faults in compliance with IEC 60825-1:2007. The laser output will
remain within Class 1 limits as long as the STMicroelectronics recommended device
settings are used and the operating conditions specified in the datasheet are respected. The
laser output power must not be increased by any means and no optics should be used with
the intention of focusing the laser beam.

Compliance
Complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice
No.50, dated June 24, 2007.
