## 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. The 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. Key Features 3-Axis Magnetic Field Sensing – Measures Bx, By, and Bz linear fields up to ±130 mT 12-Bit Resolution – High-precision digital output for each measurement axis I2C Interface – Standard 2-wire I2C up to 1 Mbit/sec, shareable with other I2C devices Accurate Angle Sensing – Excellent X/Y measurement matching for precise angular detection Onboard Voltage Regulation – 3.3V regulator and level shifting for 3V or 5V microcontrollers, with a spare 3.3V output pin STEMMA QT / Qwiic Compatible – Solderless connectors for plug-and-play setup and daisy-chaining Note: This sensor is designed for detecting nearby magnets, not for compass applications. It is not sensitive enough to measure the Earth's magnetic field. Ideal For DIY joysticks and 3D position controllers Detecting magnet-equipped objects (lids, latches, moving parts) Rotary angle and position sensing Proximity detection with magnets Package Contents 1× Adafruit TLV493D Triple-Axis Magnetometer Breakout Resources TLV493D 3D Magnetometer Demo (YouTube)
