Si72xx-EVAL-KIT Magnetic Sensor Evaluation Kit
The SI72xx-EVAL-KIT showcases the different types of sensors within the Si72xx family. The quick connect USB dongles allows the small “postage stamp” boards to be connected to a PC host and evaluated. Once connected a graphical user interface tool can show the user the output of the magnetic sensor, a small magnet is provided in the kit to easily alter the output of the sensor.
