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.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)Integrated angle CORDIC calculation: with gain and offset adjustmentSingle axis conversion rate: 20kSPSConfigurable averaging: up to 32x for noise reductionConversion trigger: by I2C or dedicated INT pinOptimized I2C interface: with cyclic redundancy check (CRC)Maximum I2C clock speed: 1-MHzSpecial I2C frame reads: for improved throughputI2C addresses: factory-programmed and user-configurable I2C addresses (must be re-written on every reset)Integrated temperature compensation: for multiple magnet typesBuilt-in temperature sensor: includedProduct Dimensions: 25.3mm x 17.7mm x 4.6mm / 1.0" x 0.7" x 0.2"Product Weight: 1.7g / 0.1ozUse a STEMMA QT or qwiic cable for solderless I2C wiring, or solder the included 0.1" header for breadboard and perfboard projects. **Product Type:** Magnetometer Breakout ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDutECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--9a87a6f2b9d68ea8a5ef554b8545ca3c1075e4c8/6489-00.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDw9ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b3d9a1983a3303fe5e7e56a9bab99c87e6855beb/6489-04.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDy9ECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0ca7ea9989b2121590e68e3a03bd93790e330239/6489-01.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD0tECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b088b1deae26acc5631ea799e297897ef237ddc3/6489-02.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD1tECSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f83a0db8b1983c04cf69ca150e0a622d8aa39f4e/6489-03.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
