The Adafruit TMAG5273 (A2) 3D Hall Effect Magnetometer is a compact, low-power sensor designed for precise magnetic field detection across three axes. It integrates independent X, Y, and Z Hall-effect sensors with a 12-bit ADC for accurate digital output via I2C communication. Featuring a built-in CORDIC engine, it enables real-time 360° angle calculations for both on-axis and off-axis measurements. This makes it ideal for rotary encoders, motion tracking, and contactless control systems. The board includes STEMMA QT connectors for easy plug-and-play integration without soldering. With support for gain and offset correction, temperature sensing, and configurable power modes, this sensor offers flexibility and reliability for industrial and embedded electronics applications requiring magnetic sensing and position detection.
