Adafruit TLV493D Triple-Axis Magnetometer - STEMMA QT / Qwiic

The TLV493D Triple-Axis Magnetometer is a compact breakout board for measuring magnetic fields across three axes. It is well suited for position sensing, angle measurement and tracking the movement of nearby magnets in 3D. With its I2C interface, it can be integrated easily into a wide range of microcontroller projects.

This breakout is built for convenient use in prototyping and embedded applications. The board includes voltage regulation and level shifting, making it suitable for both 3.3V and 5V logic systems. STEMMA QT and Qwiic connectors allow fast solderless integration, which is useful for modular sensor setups and rapid development workflows.
