VL53L0X pin functions and connections
Signal	Type	Function & connection
AVDDVCSEL	Emitter supply	Supply for the infrared VCSEL. Connection guidance Connect to the main 2.6–3.5 V rail; bypass near pins 1 and 2.
AVSSVCSEL	Emitter return	Ground for the emitter supply. Connection guidance Connect to the main ground plane.
GND	Ground	Common ground contact. Connection guidance Connect to the main ground plane.
GND2	Ground	Common ground contact. Connection guidance Connect to the main ground plane.
XSHUT	Active-low shutdown	LOW selects hardware standby. Connection guidance Drive from the host; use a 10 kΩ pull-up when host state is unknown. Never leave this input floating. Drive HIGH only with AVDD present.
GND3	Ground	Common ground contact. Connection guidance Connect to the main ground plane.
GPIO1	Open-drain interrupt	Signals a programmed measurement event. Connection guidance Use a 10 kΩ pull-up to the selected I/O rail and a host input. Leave open if unused.
DNC	Do not connect	Reserved internal contact. Connection guidance Leave floating; do not connect to ground or power.
SDA	I²C data	Bidirectional serial data. Connection guidance Pull up to the configured I/O rail; 1.5–2 kΩ is ST’s example at 2.8 V / 400 kHz.
SCL	I²C clock	Clock input from the controller. Connection guidance Use up to 400 kHz with a suitable pull-up.
AVDD	Main supply	Sensor supply. Connection guidance Connect to the same 2.6–3.5 V rail as pin 1.
GND4	Ground	Common ground contact. Connection guidance Connect to the main ground plane.

Bare sensor, not a regulated breakout module

Manufacturer-referenced values8 parameters

Scroll within the table to see all columns and rows.

Parameter	Value	Conditions / notes
AVDD and AVDDVCSEL	2.6–3.5 V	Connect to the same rail; nominal 2.8 V
Standard I/O mode	1.6–1.9 V	1.8 V nominal; API default mode
2V8 I/O mode	2.6–3.5 V	HIGH levels equal AVDD; configure via API
Ambient temperature	−20 to +70°C	Normal operating range
Active ranging current	19 mA typical	23°C / 2.8 V, default API, 33 ms budget
Peak current	Up to 40 mA	Including VCSEL
Hardware standby	5 µA typical / 7 µA maximum	At stated nominal temperature and voltage
Absolute voltage limit	−0.5 to 3.6 V	AVDD and digital I/O; stress limit, not operating range

Provide supply capacity for peak current and place the bypass capacitors close to the emitter supply pins.

Parameter	Value	Conditions / notes
Default	30 ms	1.2 m; accuracy depends on Table 12 test conditions
High accuracy	200 ms	1.2 m, better than ±3% under specified conditions
Long range	33 ms	2 m only in dark conditions without ambient IR
High speed	20 ms	1.2 m, ±5% under specified conditions
Interpretation	Budget is not a guaranteed sample period	Include host transfers and housekeeping
Validity	Check range status	Do not accept a numeric distance from a failed sample

Target reflectance, ambient light, cover glass and calibration affect performance.

Address notation and board connections

Manufacturer-referenced values7 parameters

Scroll within the table to see all columns and rows.

Parameter	Value	Conditions / notes
Default address	0x29 seven-bit	Datasheet 0x52 write / 0x53 read include the direction bit
Maximum SCL	400 kHz	Use pull-ups for the selected I/O level
SDA / SCL pull-ups	1.5–2 kΩ example	ST recommendation at AVDD=2.8 V and 400 kHz
XSHUT / GPIO1 pull-ups	10 kΩ example	GPIO1 may be open when unused; XSHUT must be driven
Multiple sensors	Use separate XSHUT control lines	Enable one at a time and assign distinct addresses after each reset
Initialization	ST API required	This is not a simple analog distance-voltage output
DNC pin 8	Leave floating	Do not use as ground or supply

The illustrated host uses 2.8 V-compatible I/O and enables the sensor’s 2V8 mode.

Keep the optical path clear

Parameter	Value	Conditions / notes
Emitter	940 nm VCSEL	Invisible infrared source
Receiver	SPAD array	Single-photon avalanche-diode technology
Package height	1.0 mm nominal	4.4 × 2.4 mm outline
Cover glass	Offset and crosstalk calibration	Follow ST optical-window and exclusion-cone guidance
Reference calibration	Follow API sequence	Required for the target design
Distance equation	d = c × t / 2	Conceptual round-trip relation; internal algorithms handle timing
500 mm illustration	About 3.34 ns round trip	Physics illustration, not an accessible host timer reading

Do not obscure either optical aperture with labels, paint or board hardware.
