{"title":"Adafruit TLV493D Triple-Axis Magnetometer - STEMMA QT / Qwiic","handle":"adafruit-tlv493d-triple-axis-magnetometer-stemma-qt-qwiic","url":"/products/adafruit-tlv493d-triple-axis-magnetometer-stemma-qt-qwiic","description":"The Adafruit TLV493D is a 3-axis magnetometer designed for detecting and tracking nearby magnets in three dimensions. Manufactured by Infineon, this sensor measures magnetic fields across the X, Y, and Z axes with 12-bit resolution — ideal for applications like DIY joysticks, position sensing, or detecting the movement of magnet-equipped objects.\n\nThe breakout board includes an onboard voltage regulator and logic level shifting for compatibility with both 3.3V and 5V microcontrollers. STEMMA QT / Qwiic connectors on both sides allow solderless I2C connections and easy daisy-chaining with other sensors. Arduino and CircuitPython/Python libraries are available for quick setup.\n\nKey Features\n\n\n3-Axis Magnetic Field Sensing – Measures Bx, By, and Bz linear fields up to ±130 mT\n\n12-Bit Resolution – High-precision digital output for each measurement axis\n\nI2C Interface – Standard 2-wire I2C up to 1 Mbit/sec, shareable with other I2C devices\n\nAccurate Angle Sensing – Excellent X/Y measurement matching for precise angular detection\n\nOnboard Voltage Regulation – 3.3V regulator and level shifting for 3V or 5V microcontrollers, with a spare 3.3V output pin\n\nSTEMMA QT / Qwiic Compatible – Solderless connectors for plug-and-play setup and daisy-chaining\n\n\n\nNote: This sensor is designed for detecting nearby magnets, not for compass applications. It is not sensitive enough to measure the Earth's magnetic field.\n\n\nIdeal For\n\nDIY joysticks and 3D position controllers\nDetecting magnet-equipped objects (lids, latches, moving parts)\nRotary angle and position sensing\nProximity detection with magnets\n\n\nPackage Contents\n\n1× Adafruit TLV493D Triple-Axis Magnetometer Breakout\n\n\nResources\n\nTLV493D 3D Magnetometer Demo (YouTube)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4947,"title":"Default Title","sku":"AF-4366","price":12.14,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
