Description​

RAK12044 is a WisBlock Hall Effect Sensor module that extends the WisBlock system with a DRV5056A4QDBZR Hall Sensor from Texas Instruments. It comes with a ready-to-use software library and tutorial, making it easy to build a magnetic field data acquisition system. Magnetic field data is interfaced via I2C. Additionally, the RAK12044 can be mounted to the sensor slot of the WisBlock Base board.
