Specifications
- TypeParameter
- Packaging
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
Bulk - Series
In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.
FlightSense™ - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures
1 (Unlimited) - Voltage - Supply
Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.
2.8V~5V - Base Part Number
The "Base Part Number" (BPN) in electronic components serves a similar purpose to the "Base Product Number." It refers to the primary identifier for a component that captures the essential characteristics shared by a group of similar components. The BPN provides a fundamental way to reference a family or series of components without specifying all the variations and specific details.
VL53L1 - Utilized IC / Part
Utilized IC / Part is a parameter that refers to the extent to which an integrated circuit (IC) or electronic component is being used or consumed within a system or application. It typically indicates the percentage or ratio of the component's capabilities that are being utilized in a given scenario. This parameter is important for assessing the efficiency and performance of the component, as well as for determining if the component is being underutilized or overburdened in a particular application. Monitoring and optimizing the utilization of ICs and electronic parts can help improve overall system reliability, efficiency, and cost-effectiveness.
VL53L1X - Supplied Contents
Supplied Contents in electronic components refers to the items or materials that are included with the component when it is purchased. These contents can vary depending on the specific component and manufacturer, but typically include things like user manuals, installation guides, cables, connectors, and any additional accessories needed for the component to function properly. The supplied contents are important for ensuring that the user has everything they need to set up and use the electronic component correctly. It is recommended to carefully check the supplied contents upon receiving a new electronic component to make sure that nothing is missing and to familiarize oneself with the included materials for optimal use.
Board(s) - Sensor Type
In electronic components, the parameter "Sensor Type" refers to the specific type of sensor technology used in a particular component to detect and measure physical phenomena such as light, temperature, pressure, motion, or proximity. Different sensor types utilize various principles and mechanisms to convert the detected input into an electrical signal that can be processed by the electronic component. Common sensor types include photodiodes, thermistors, accelerometers, and proximity sensors, each designed for specific applications and environments. Understanding the sensor type is crucial for selecting the right component for a given task and ensuring accurate and reliable sensing capabilities in electronic systems.

VL53L1X Application Diagram

VL53L1X Applications
• User detection (Autonomous low-power mode) to power on/off and lock/unlock devices like personal computers/laptops and the IoT.
• Service robots and vacuum cleaners (long distance and fast obstacle detection)
• Drones (landing assistance, hovering, ceiling detection)
• Smart shelves and vending machines (goods inventory monitoring)
• Sanitary (robust user detection whatever the target reflectance)
• Smart building and smart lighting (people detection, gesture control)
• 1 D gesture recognition
• Laser assisted autofocus which enhances the camera autofocus system speed and robustness, especially in difficult scenes (low light and low contrast) and video focus tracking assistance.
VL53L1X Distance mode
The VL53L1X has three distance modes (DM): short, medium, and long.
Long distance mode allows the longest possible ranging distance of 4 m to be reached. However, this maximum ranging distance is impacted by ambient light. Short distance mode is more immune to ambient light, but its maximum ranging distance is typically limited to 1.3 m.

VL53L1X Breakable Board
The breakout boards can be broken along the red dotted line as shown in the figure below, to use the “mini PCB”. This set up is easier to integrate into a customer device due to its small form factor.

What is vl53l1x?
The VL53L1X is a state-of-the-art, Time-of-Flight (ToF), laser-ranging sensor, enhancing the ST FlightSense™ product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz.
How does the VL53L1X work?
Unlike conventional IR sensors that use the intensity of reflected light to estimate the distance to an object, the VL53L1X uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector.
How do I change my address on I2C?
To summarize the document: 1.Put all the Vl53L1x chips on the same I2C bus. 2.Connect each reset button to a separate I/O pin. 3.Change the address of the sensors one at a time.
