{"title":"Adafruit TMAG5273 A2 3D Hall Effect Magnetometer Breakout","handle":"adafruit-tmag5273-a2-3d-hall-effect-magnetometer","url":"/products/adafruit-tmag5273-a2-3d-hall-effect-magnetometer","description":"This breakout carries the TMAG5273 A2, a low-power linear 3D Hall-effect sensor for measuring magnetic fields across the X, Y and Z axes. Its built-in 12-bit ADC provides axis readings over I2C, and there is also an integrated thermometer for basic temperature measurement.The sensor includes an angle calculation engine (CORDIC) for full 360° angular position information, using two user-selected magnetic axes over I2C. It is well suited to rotation and motion sensing with an embedded magnet, such as magnetic rotary encoders and joysticks without mechanical switches.Adafruit has added the support circuitry needed for use with 3.3V boards such as Feather and Raspberry Pi, or 5V boards such as Arduino and Metro328. STEMMA QT connectors make solder-free I2C wiring possible with compatible cables, while the standard header is included for breadboard or perfboard use.The board is fully assembled and tested, with CircuitPython/Python and Arduino drivers available for getting magnetic measurements quickly. Four 2.5mm (0.1\") mounting holes are included for easy attachment.Specifications:Configurable power modes: includingActive mode current: 2.3mAWake-up and sleep mode current: 1µASleep mode current: 5nASelectable linear magnetic range at X, Y, or Z axis: selectableTMAG5273x1: ±40mT, ±80mTTMAG5273x2: ±133mT, ±266mTInterrupt signal: from user-defined magnetic and temperature threshold crossSensitivity drift: 5% (typical)Angle calculation: Integrated angle CORDIC calculation with gain and offset adjustmentSingle axis conversion rate: 20kSPSAveraging: Configurable averaging up to 32x for noise reductionConversion trigger: by I2C or dedicated INT pinI2C interface: Optimized I2C interface with cyclic redundancy check (CRC)Maximum I2C clock speed: Maximum 1-MHz I2C clock speedI2C frame reads: Special I2C frame reads for improved throughputI2C addresses: Factory-programmed and user-configurable I2C addresses (must be re-written on every reset)Temperature compensation: Integrated temperature compensation for multiple magnet typesTemperature sensor: Built-in temperature sensorProduct Dimensions: 25.5mm x 17.7mm x 4.6mm / 1.0\" x 0.7\" x 0.2\"Product Weight: 1.7g / 0.1ozThis A2 version is intended for stronger ferric or rare-earth magnets, rather than measuring the Earth’s magnetic field.","vendor":"Adafruit","product_type":"Magnetometer Sensor","in_stock":true,"options":[],"variants":[{"id":16367,"title":"Default Title","sku":"AF-6490","mpn":"ADA6490","price":14.2,"on_sale":false,"in_stock":true,"available_quantity":95}]}
