This board is perfect for applications involving magnetic proximity detection, door and window sensing, mobile rotor and control, and more, all on a Mini 0.5in. 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 (1µA in sleep mode), a high precision of ±0.5% typical accuracy, 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! This board version is also presented in our Qwiic Mini footprint for those who need more project space or weight to work with! However, if you would prefer, the I2C pins are also broken out to standard 0.1in.-spaced pins. The SparkFun Qwiic Connect System is 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 can’t hook it up wrong.
