The built-in 12-bit ADC can read the signal from each axis for read-out over I2C, it even has a thermometer built in for basic temperature reading!\u003c\/p\u003e\n\u003cp\u003eAn integrated angle calculation engine (CORDIC) provides full 360° angular position information for both on-axis and off-axis angle measurements. The angle calculation is performed using two user-selected magnetic axes over I2C. The TMAG also features magnetic gain and offset correction - note you'll have to manage the values and write them into the chip on boot-up.\u003c\/p\u003e\n\u003cp\u003e3D Hall effect sensors are great for sensing rotation or motion of an object nearby with a magnet embedded inside: often used for magnetic rotary encoders or joysticks that don't have mechanical switches and thus are more reliable and don't fail from wear.\u003c\/p\u003e\n\u003cp\u003eThis sensor comes in two flavors, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eA1\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003etype is ±40mT \/ ±80mT range (you can pick either range), and the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eA2\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003ehas a wider ±133mT \/ ±266mT range. Both use the exact same firmware and pinout - the firmware we've written can detect which one you have plugged in and automatically scale the readings as necessary. This isn't a great sensor for measuring the magnetic field of the earth, much better for magnets of the ferric or rare-earth persuasion.\u003c\/p\u003e\n\u003cp\u003eTo make life easier so you can focus on your important work, we've taken the TMAG5723 and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (Feather\/Raspberry Pi) or 5V (Arduino\/ Metro328) logic levels. Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!).  We've even included \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eSparkFun qwiic\u003c\/a\u003e compatible\u003cstrong\u003e \u003ca rel=\"noopener\" href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\" target=\"_blank\"\u003eSTEMMA QT\u003c\/a\u003e\u003c\/strong\u003e connectors for the I2C bus so \u003cstrong\u003eyou don't even need to solder!\u003c\/strong\u003e Just wire up to your favorite micro and you can use our CircuitPython\/Python or \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_TMAG5273\"\u003eArduino drivers to easily interface with the TMAG\u003c\/a\u003e and get magnetic measurements ASAP.\u003c\/p\u003e\n\u003cp\u003eIt's fully assembled and tested.  Comes with a bit of 0.1\" standard header in case you want to use it with a breadboard or perfboard.  Four 2.5mm (0.1\") mounting holes for easy attachment.\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConfigurable power modes including:\u003cbr\u003e2.3mA active mode current\u003cbr\u003e1µA wake-up and sleep mode current\u003cbr\u003e5nA sleep mode current\u003c\/li\u003e\n\u003cli\u003eSelectable linear magnetic range at X, Y, or Z axis:\u003cbr\u003eTMAG5273x1: ±40mT, ±80mT\u003cbr\u003eTMAG5273x2: ±133mT, ±266mT\u003c\/li\u003e\n\u003cli\u003eInterrupt signal from user-defined magnetic and temperature threshold cross\u003c\/li\u003e\n\u003cli\u003e5% (typical) sensitivity drift\u003c\/li\u003e\n\u003cli\u003eIntegrated angle CORDIC calculation with gain and offset adjustment\u003c\/li\u003e\n\u003cli\u003e20kSPS single axis conversion rate\u003c\/li\u003e\n\u003cli\u003eConfigurable averaging up to 32x for noise reduction\u003c\/li\u003e\n\u003cli\u003eConversion trigger by I2C or dedicated INT pin\u003c\/li\u003e\n\u003cli\u003eOptimized I2C interface with cyclic redundancy check (CRC):\u003cbr\u003eMaximum 1-MHz I2C clock speed\u003cbr\u003eSpecial I2C frame reads for improved throughput\u003cbr\u003eFactory-programmed and user-configurable I2C addresses (must be re-written on every reset)\u003c\/li\u003e\n\u003cli\u003eIntegrated temperature compensation for multiple magnet types\u003c\/li\u003e\n\u003cli\u003eBuilt-in temperature sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 25.3mm x 17.7mm x 4.6mm \/ 1.0\" x 0.7\" x 0.2\"\u003c\/p\u003e\n\u003cp\u003eProduct Weight: 1.7g \/ 0.1oz\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"80\" width=\"145\" alt=\"RoHS 2 2011 65 EU Compliant\" src=\"https:\/\/www.adafruit.com\/includes\/templates\/shop2019\/images\/RoHS2_2011_65_EU.svg\"\u003e \u003cimg height=\"80\" width=\"145\" alt=\"RoHS 2 2015 863 EU Compliant\" src=\"https:\/\/www.adafruit.com\/includes\/templates\/shop2019\/images\/RoHS2_2015_863_EU.svg\"\u003e\u003c\/p\u003e\n\u003ch2\u003eLearn\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-tmag5273-3d-hall-effect-magnetometer-breakout\"\u003ePrimary Guide: Adafruit TMAG5273 3D Hall Effect Magnetometer Breakout\u003c\/a\u003e 3D orientation detection over I2C\u003c\/li\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" href=\"https:\/\/learn.adafruit.com\/products\/6489\/guides\" target=\"_blank\"\u003eSee All Guides\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"A1 (±40mT \/ ±80mT)","offer_id":57562981695861,"sku":"ADA6489","price":4.75,"currency_code":"GBP","in_stock":true},{"title":"A2 (±133mT \/ 266mT)","offer_id":57562981728629,"sku":"ADA6490","price":4.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0389\/1025\/files\/6489-00.png?v=1789039255","url":"https:\/\/wholesale.pimoroni.com\/en-au\/products\/adafruit-tmag5273-3d-hall-effect-magnetometer-breakout-stemma-qt","provider":"Pimoroni Wholesale","version":"1.0","type":"link"}
