It uses an 8×8 Time-of-Flight matrix to return depth data from 64 points, giving your robot or interactive project a much better sense of what is in front of it.Onboard firmware runs on an RP2040 microcontroller, so the module can deliver real-time ranging data without needing a powerful host processor. It suits obstacle avoidance, drop-off detection, contactless gesture control, reactive lighting and smart automation projects.It is designed for maker-friendly connection across Arduino, micro:bit, ESP32, Raspberry Pi, LattePanda and UNIHIKER K10 projects, with Gravity-I2C, UART and USB-C connection options. Libraries and tutorials are available for Arduino IDE, Mind+ and MakeCode, and the four selectable I2C addresses allow up to four sensors to be daisy-chained.The kit includes the Gravity: Matrix Laser Ranging Sensor ×1, PH2.0-4P Connection Cable ×1, Aluminum Alloy Mounting Bracket ×1, Aluminum Alloy Support Bracket ×1, M3 Thumb Screw ×4, M3 Sensor Fixing Screw ×2 and M3×35 Mounting Copper Spacer ×2. During the current version upgrade period, new and old hardware versions may be shipped randomly.Features:3D depth perception: Generates a 64-pixel depth map that provides context such as obstacles, open paths and table edges.Low power consumption: Offers a low-power 3D vision option for maker and robotics projects.Plug-and-play compatibility: Designed for straightforward use in robotics, interactive art, gesture recognition and smart automation.Supported Platforms: Arduino, micro:bit, ESP32, Raspberry Pi, LattePanda, UNIHIKER K10.Supported Programming Methods: Whether using the Arduino IDE, or graphical editors like Mind+ and MakeCode, libraries and tutorials are available.Connection Options: Support Gravity-I2C / UART / USB-C.Cascading Support: The 4 switchable I2C addresses let you daisy-chain up to four sensors together for a massive field of view.Expandable platform: The onboard RP2040 processor allows developers to load custom firmware or run lightweight machine learning models (TinyML).Advanced sensing: Can be used to recognise specific gestures, detect movement patterns, or add new features directly on the sensor itself.Open-source development: Open-source schematics and comprehensive documentation support advanced robotics, IoT and AI-driven applications.Hardware Upgrade (Eco-friendly & Safe): To comply with EN71 standards, the original yellow copper spacers and silver/copper thumb screws have been upgraded to black aluminum versions.Firmware Upgrade (V1.3): The firmware has been updated from V1.2 to V1.3.Firmware bug fix: This update resolves a bug where invalid distance values would remain fixed (unchanged) when the target exceeded the measurement range.Robotics Navigation: Smooth obstacle avoidance and drop-off detection.Gesture Control: Reliable contactless interaction for smart devices.Interactive Installations: Artistic displays such as “following eyes” or reactive lighting.Smart Automation: Directional entryway monitoring and intelligent room sensing.Specifications:Sensor Model: VL53L7CXAlgorithm Processing MCU: RP2040Number of Matrices: 8×8, totaling 64 ranging pointsRanging Mode: Continuous RangingRanging Speed: 15Hz - 60HzRanging Range: 20mm - 3500mmRanging Accuracy (20 - 200mm): ±11mm for white targets, ±12mm for light gray targets, and ±12mm for gray targets;Ranging Accuracy (200 - 3500mm): ±5% for white targets, ±6% for light gray targets, and ±6% for gray targets.Ranging Angle: 60° horizontal, 60° vertical, 90° diagonalLaser Safety Class: Compliant with Class 1 laser safety standardsOperating Voltage: 3.3V - 5VOperating Current: Less than 80mAData Interface: I2C/UART/USBInterface Type: PH2.0-4P (Gravity Pinout)I2C Address: 4 adjustable options: 0x30/0x31/0x32/0x33UART Baud Rate: 115200bps (fixed value, non-modifiable)Firmware Update: TYPE-C, USB flash drive modeA good fit for small robots, room sensing, contactless controls and installations where a 64-point depth map is more useful than a single distance reading.","vendor":"DFRobot","product_type":"Distance Sensor","in_stock":true,"options":[],"variants":[{"id":15652,"title":"Default Title","sku":"DF-SEN0628","mpn":"SEN0628","price":52.51,"on_sale":false,"in_stock":true,"available_quantity":387}]}
