Built on a standard 25.4 × 25.4 mm (1 × 1 in) Qwiic breakout, it communicates over I²C with no soldering required.\n\nThe Texas Instruments TMAG5273 features a configurable linear magnetic range (±40 mT or ±80 mT), an integrated angle calculation engine (CORDIC) with gain and offset adjustment, magnetic tamper detection, and wake-up/threshold interrupts. A built-in temperature sensor and disable button are also included on the breakout.\n\nKey Features\n\n\n3D Magnetic Field Sensing – Measures field strength and direction across X, Y, and Z axes\n\nConfigurable Range – ±40 mT (820 LSB/mT) or ±80 mT (410 LSB/mT)\n\nHigh Precision – ±0.5° rotational accuracy over 360°\n\nUltra-Low Power – 2.3 mA active, 1 µA wake-up/sleep, 5 nA deep sleep\n\nBuilt-In Temperature Sensor – Range −40 °C to +170 °C with compensation\n\nQwiic I²C Interface – Two horizontal Qwiic connectors; default address 0x35\n\nInterrupt Pin – Configurable threshold and tamper detection alerts\n\nDisable Button – On-board button to disable the sensor\n\n\nSpecifications\n\n\nSensor – Texas Instruments TMAG5273\n\nVoltage Range – 1.7–3.6 V\n\nI²C Address – 0x35 (default, configurable)\n\nMagnetic Drift – 5%\n\nOperating Temperature – −40 °C to +125 °C\n\nConfigurable Data Rate – With CRC support\n\nBoard Dimensions – 25.4 × 25.4 mm\n\nMounting – Four 4-40 screw holes\n\nBreakout Pins – 3V3, GND, SCL, SDA, INT, Disable\n\n\nIdeal For\n\nMagnetic proximity and position detection\nDoor and window sensing\nMotor rotor position and control\nTamper detection and security applications\nRotary encoder and joystick sensing\n\n\nPackage Contents\n\n1× SparkFun Linear 3D Hall-Effect Sensor Breakout (TMAG5273, Qwiic)\n\n\nResources\n\nHookup Guide\nSchematic (PDF)\nEagle Files\nBoard Dimensions (PDF)\nTMAG5273 Datasheet (PDF)\nArduino Library (GitHub)\nHardware Design (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":1207,"title":"Default Title","sku":"SF-SEN-23880","mpn":"SEN-23880","price":14.74,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
