The SparkFun TMAG5273 Qwiic Linear 3D Hall-Effect Sensor is a low-power, high-precision magnetic field sensor that can detect a magnetic field's presence, strength, and direction in three dimensions. Ideal for magnetic proximity detection, door and window sensing, mobile rotor control, and more, this board fits perfectly into a compact 2.54cm x 2.54cm Qwiic breakout.The TMAG5273 from Texas Instruments features a configurable linear magnetic range of either ±40 mT or ±80 mT, along with TI's integrated angle calculation engine (CORDIC) for gain and offset adjustments. It includes magnetic tamper detection and configurable wake-up/threshold settings that can trigger interrupts via the I²C interface or a dedicated interrupt pin.With a power consumption of just 2.3mA in Active Mode (1µA in sleep mode), a high precision of ±0.5% typical accuracy, a Disable button, and a built-in temperature sensor, the TMAG5273 is an excellent choice for anyone needing a low-power, high-precision magnetic field sensor.Communication is handled via I²C, with pins broken out to the Qwiic system, eliminating the need for soldering. For those who prefer, the I²C pins are also available on standard 2.54mm-spaced pins.Features:Breakout Board * Dimensions: 2.54cm x 2.54cm standard footprint * Two horizontal Qwiic connectors * Four mounting holes compatible with 4-40 screws * Six PTH pins: 3V3, GND, SCL, SDA, INT, Disable * Power LED (Red) * Disable button TMAG5273 Hall Effect Sensor * Configurable I²C address: 0x35 (Default) (7-bit) * Magnetic range (sensitivity): ±40mT (820 LSB/mT) or ±80mT (410 LSB/mT) * Magnetic drift: 5% * Rotational accuracy: ±0.5°/360° rotation * Voltage range: 1.7 - 3.6V * Power consumption: Sleep: 5nA, Wake-Up/Sleep: 1µA, Active: 2.3mA * Operating temperature: –40 - 125°C * Integrated temperature compensation/measurement range: -40 - 170°C * Configurable data rate with CRC support Documents: * Schematic * Eagle Files * Board Dimensions * Hookup Guide * Datasheet (TMAG5273) * Qwiic Info Page * TMAG5273 Arduino Library * GitHub Hardware Repo Videos https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-01-24 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-09-28 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-10-02 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-10-09 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-10-31 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-12-03 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-12-19 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2025-12-24 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-01-04 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-01-23 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-01-28 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-01-31 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-02-16 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-02-24 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-03-03 https://elecena.pl/product/27751469/sparkfun-linear-3d-hall-effect-sensor-tmag5273-qwiic 2026-04-13
