This breakout makes it easy to add 3D Hall-effect magnetic sensing to a microcontroller project. The TMAG5273 integrates independent X, Y and Z Hall-effect sensors with a 12-bit ADC, giving you magnetic measurements over I2C plus a built-in temperature sensor for basic temperature readings.
It is well suited to detecting the rotation or motion of a nearby object with an embedded magnet, such as magnetic rotary encoders and non-contact joystick mechanisms. The integrated CORDIC angle calculation engine can provide 360° angular position information using two user-selected magnetic axes.
This A1 version supports selectable ±40mT or ±80mT ranges. The breakout includes level-shifting support for 3.3V and 5V logic, STEMMA QT / qwiic-compatible I2C connectors, standard header for breadboard use, and four 2.5mm mounting holes.
The board is fully assembled and tested, and works with Adafruit CircuitPython/Python and Arduino drivers to get readings quickly.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- 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.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- 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.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
- 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.
