Wiring the TLV493D is easy, since it only requires power and two wires for an I2C connection. Additionally, the STEMMA QT connectors give you additional solderless options for wiring:
Fortunately Infineon have written a library for you for the TLV493D which you can install using the Arduino IDE's Library Manager:
Click the Manage Libraries ... menu item, search for Infineon TLV493, and select theTLV493D-A1B6 library:
Infineon has provided a few examples, but the simplest example is the "Cartesian" example which reads the X, Y, and Z axis measurements in milli-teslas (mT).
Open the example by navigating to the appropriate spot in the examples submenu:
Once you compile and upload the example to your Arduino compatible board of choice, open the serial monitor, verify that your baud rate setting matches the example, and you should see measurements for the three axes being printed. If you wave a magnet near the sensor you can see the values changing!
