The TMF8820 provides 3×3 multi-zone output with multi-object detection and a dynamically adjustable field of view up to 63° diagonal — all processed on-chip and delivered over I2C.\n\nThe onboard optical filter blocks ambient light, enabling reliable distance measurements in both dark and bright sunlight conditions. Connect via SparkFun's Qwiic system for solderless setup, or use the broken-out 0.1\" header pins for breadboard prototyping.\n\nKey Features\n\n\n5m Detection Range – 10mm to 5000mm at up to 30Hz\n\n3×3 Multi-Zone – Configurable zones with multi-object detection\n\nAdjustable Field of View – Up to 63° diagonal\n\nClass 1 Laser – 940nm VCSEL light source (eye-safe, IEC 60825-1 2014)\n\nOn-Chip Processing – Distance and confidence values output directly\n\nSunlight Rejection – High-performance optical filter and algorithm\n\nQwiic / I2C Interface – Two Qwiic connectors, I2C address 0x41\n\n2.7V to 3.6V Operation – 8µA standby, 57mA active\n\nConfigurable Jumpers – Power LED and I2C pull-ups\n\n2× GPIO + Enable Pin – Broken out as PTH pads\n\nBoard Size – Qwiic Standard 1.0\" × 1.0\" (25.4mm × 25.4mm)\n\n\n\nNote: Requires a microcontroller with sufficient flash memory. ATmega328P-based boards (Arduino Uno) are not supported. Use an ESP32 or comparable board with larger RAM.\n\n\nIdeal For\n\nCamera autofocus (Laser Detect Autofocus)\nPresence detection for computing devices\nObject detection and collision avoidance in robotics\nIndustrial light curtain applications\n\n\nPackage Contents\n\n1× SparkFun Qwiic dToF Imager - TMF8820\n\n\nResources\n\nHookup Guide (SparkFun)\nTMF882X Datasheet (PDF)\nDriver User Guide (PDF)\nHost Driver Communication (PDF)\nSchematic (PDF)\nArduino Library (GitHub)\nHardware Repo (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2253,"title":"Default Title","sku":"SF-SEN-19036","price":32.15,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
