The SparkFun TMAG5273 Qwiic Mini Linear 3D Hall-Effect Sensor is a low-power, high-precision magnetic field sensor that can detect a magnetic field's presence, strength, and direction in three dimensions. This board is perfect for applications involving magnetic proximity detection, door and window sensing, mobile rotor and control, and more, all on a Mini 0.5in. x 1in. Qwiic breakout!

The TMAG5273 from Texas Instruments possesses a linear magnetic range configurable to either ±40 mT or ±80 mT and TI's integrated angle calculation engine (CORDIC) with gain and offset adjustment to be used in various applications. In addition, the included magnetic tamper detection and wake-up/threshold settings can be configured to trigger interrupts through the I²C interface or only with the dedicated interrupt pin.

With a low power consumption rate of only 2.3mA in Active Mode (1µA in sleep mode), a high precision of ±0.5% typical accuracy, and a built-in temperature sensor, the SparkFun TMAG5273 Linear 3D Hall-Effect board is a great and economical choice for anyone who needs a low-power, high-precision magnetic field sensor.

The Linear 3D Hall-Effect Sensor communicates via I²C, so we've broken out each of those pins to our Qwiic system, so no soldering is required to connect it to the rest of your system! This board version is also presented in our Qwiic Mini footprint for those who need more project space or weight to work with! However, if you would prefer, the I²C pins are also broken out to standard 0.1in.-spaced pins.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Jargon buster

Plain-language definitions for the technical terms used above.

breakout: A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
Hall-effect sensor: A magnetic sensor that changes its output when it detects a magnetic field. It matters for projects that need to sense magnets, wheel rotation, position, or current without physical contact.
LED: A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
LSB: Least significant bit (LSB) is the lowest-order bit in a binary number, the bit that some serial protocols send first or last. In analogue-to-digital and digital-to-analogue converters, one LSB also means the smallest step the device can resolve, equal to its full-scale range divided by the number of steps.
PCB: A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
PTH: Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
Qwiic: Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
Temperature compensation: Temperature compensation is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
