It uses the time of flight (ToF) of invisible, eye-safe laser pulses to measure absolute distances to \u003cstrong\u003emultiple targets\u003c\/strong\u003e simultaneously, independent of ambient lighting conditions and target characteristics like color, shape, and texture (though these things will affect the maximum range).  Distance measurements can be read through a digital I²C interface. The board includes a 2.8 V linear regulator and level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.  \u003cstrong\u003eNote:\u003c\/strong\u003e This is \u003cins\u003enot recommended\u003c\/ins\u003e for use with 8-bit MCUs; for such applications, consider the \u003ca href=\"https:\/\/www.pololu.com\/product\/3415\"\u003eVL53L1X\u003c\/a\u003e, \u003ca href=\"https:\/\/www.pololu.com\/product\/2490\"\u003eVL53L0X carrier\u003c\/a\u003e, or \u003ca href=\"https:\/\/www.pololu.com\/product\/2489\"\u003eVL6180X carrier\u003c\/a\u003e.\u003c\/p\u003e\n\u003cbr\u003e\u003cp class=\"note_warning\"\u003e\u003cstrong\u003eNote: this product is not recommended for use with 8-bit microcontrollers,\u003c\/strong\u003e and we also therefore do not provide support for it in the form of Arduino libraries as we do our other time-of-flight sensors. The VL53L3CX does not directly provide distance measurements.  Instead, it provides histogram data that can be processed with algorithms provided by ST.  This processing requires a significant amount of RAM and code space, making this sensor impractical for use with a typical 8-bit microcontroller.  (For example, a program we compiled for an STM32F4 microcontroller that does little more than get readings from the VL53L3CX uses 63 KB of flash and 14 KB of global variables in RAM.)

This board is a carrier for the VL53L3CX , so we recommend careful reading of the \u003ca href=\"\/file\/0J1765\/vl53l3cx.pdf\"\u003eVL53L3CX datasheet\u003c\/a\u003e (1MB pdf) before using this product.\u003c\/p\u003e\n\u003cp\u003eThe VL53L3CX is effectively a tiny, self-contained lidar system featuring an integrated 940 nm Class 1 laser, which is invisible and eye-safe.  Unlike conventional IR sensors that use the intensity of reflected light to estimate the distance to an object, the VL53L3CX uses ST’s FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the objects and be reflected back to a detector.  This approach ensures absolute distance measurements independent of ambient lighting conditions and target characteristics (e.g. color, shape, texture, and reflectivity), though these external conditions do affect the maximum range of the sensor.\u003c\/p\u003e\n\u003cp\u003eUnder favorable conditions, the sensor can report distances up to 5 m (16 ft) with 1 mm resolution.  The minimum ranging distance is 10 mm.  Ranging measurements are available through the sensor’s I²C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output.\u003c\/p\u003e\n\u003cp\u003eThe VL53L3CX is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use.  It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.\u003c\/p\u003e\n\u003cp\u003eThe carrier board includes a low-dropout linear voltage regulator that provides the 2.8 V required by the VL53L3CX and allows the sensor to be powered from a 2.6 V to 5.5 V supply.  The regulator output is available on the VDD pin and can supply around 100 mA to external devices. The breakout board also includes a circuit that shifts the I²C clock and data lines to the same logic voltage level as the supplied VIN, making it simple to interface the board with 3.3 V or 5 V systems, and the board’s 0.1″ pin spacing makes it easy to use with standard \u003ca href=\"https:\/\/www.pololu.com\/category\/28\/solderless-breadboards\"\u003esolderless breadboards\u003c\/a\u003e and 0.1″ perfboards.

They all function as tiny lidar systems featuring an integrated 940 nm Class 1 (i.e. invisible and eye-safe) laser, and they are all based on the same FlightSense technology, which precisely measures how long it takes for emitted pulses of infrared laser light to reach the objects and be reflected back to a detector. This approach ensures absolute distance measurements independent of ambient lighting conditions and target characteristics (e.g. color, shape, texture, and reflectivity), though these external conditions do affect the maximum range of the sensor.  These sensors are all capable of 1 mm resolution, with some limitations on some versions.\u003c\/p\u003e\n\u003cstyle type=\"text\/css\"\u003e\ntable.active_controller_comparison td.spacer {border:

5 V systems (thanks to their integrated linear regulators and level-shifters), and they are all controlled through an I²C interface.  However, they have different APIs and memory requirements, so software will generally need to be rewritten when switching between sensors in an application, and versions with higher memory requirements are generally not suitable for use with typical 8-bit microcontrollers.\u003c\/p\u003e","brand":"Pololu","offers":[{"title":"2-4 Settimane","offer_id":47696610853209,"sku":"POL-3416","price":24.81,"currency_code":"EUR","in_stock":true},{"title":"1 Giorno","offer_id":47885967884633,"sku":"POL-3416\/A","price":24.81,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/1009\/7753\/files\/0J10929.1200.jpg?v=1705454535","url":"https:\/\/robot-italy.com\/products\/3416-vl53l3cx-time-of-flight-multi-target-distance-sensor-carrier-with-voltage-regulator-500cm-max","provider":"Robot Italy","version":"1.0","type":"link"}
