## Description

The SparkFun TMAG5273 Linear 3D Hall-Effect Sensor is a low-power, high-precision magnetic field sensor that detects the presence, strength, and direction of magnetic fields in three dimensions. Built on a standard 25.4 × 25.4 mm (1 × 1 in) Qwiic breakout, it communicates over I²C with no soldering required. The 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. Key Features 3D Magnetic Field Sensing – Measures field strength and direction across X, Y, and Z axes Configurable Range – ±40 mT (820 LSB/mT) or ±80 mT (410 LSB/mT) High Precision – ±0.5° rotational accuracy over 360° Ultra-Low Power – 2.3 mA active, 1 µA wake-up/sleep, 5 nA deep sleep Built-In Temperature Sensor – Range −40 °C to +170 °C with compensation Qwiic I²C Interface – Two horizontal Qwiic connectors; default address 0x35 Interrupt Pin – Configurable threshold and tamper detection alerts Disable Button – On-board button to disable the sensor Specifications Sensor – Texas Instruments TMAG5273 Voltage Range – 1.7–3.6 V I²C Address – 0x35 (default, configurable) Magnetic Drift – 5% Operating Temperature – −40 °C to +125 °C Configurable Data Rate – With CRC support Board Dimensions – 25.4 × 25.4 mm Mounting – Four 4-40 screw holes Breakout Pins – 3V3, GND, SCL, SDA, INT, Disable Ideal For Magnetic proximity and position detection Door and window sensing Motor rotor position and control Tamper detection and security applications Rotary encoder and joystick sensing Package Contents 1× SparkFun Linear 3D Hall-Effect Sensor Breakout (TMAG5273, Qwiic) Resources Hookup Guide Schematic (PDF) Eagle Files Board Dimensions (PDF) TMAG5273 Datasheet (PDF) Arduino Library (GitHub) Hardware Design (GitHub)
