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. This board is perfect for applications involving magnetic proximity detection, door and window sensing, mobile rotor and control, and more, all on a Standard 1in. x 1in. Qwiic breakout!The TMAG5273 from Texas Instruments possesses a linear magnetic range configurable to either 40 mT or 80 mT and TI’s integrated angle calculation engine (CORDIC) with gain and offset adjustment to be used in various applications. In addition, the included magnetic tamper detection and wake-up/threshold settings can be configured to trigger interrupts through the I2C interface or only with the dedicated interrupt pin.With a low power consumption rate of only 2.3mA in Active Mode (1A in sleep mode), a high precision of 0.5% typical accuracy, a Disable button (tied to the pin with the same name), and a built-in temperature sensor, the SparkFun TMAG5273 Linear 3D Hall-Effect board is a great and economical choice for anyone who needs a low-power, high-precision magnetic field sensor.The Linear 3D Hall-Effect Sensor communicates via I2C, so we’ve broken out each of those pins to our Qwiic system, so no soldering is required to connect it to the rest of your system! However, if you would prefer, the I2C pins are also broken out to standard 0.1in.-spaced pins.TheSparkFun Qwiic Connect Systemis an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you cant hook it up wrong.SpecificationsBreakout BoardDimensions: 1in. x 1in.
