특징

3D Hall 11 Click as its foundation uses the TMAG5273, a 3D linear Hall-effect sensor used to detect the strength of a magnetic field in all three dimensions (X, Y, and Z axes) in a range up to ±40mT or ±80mT from Texas Instruments. A precision analog signal chain and an integrated 12-bit ADC enable high accuracy and low drift magnetic field measurements while supporting a sampling of up to 20kSPS. It also has an integrated temperature sensor available for multiple system functions, such as thermal budget check or temperature compensation calculation for a given magnetic field. The output signals (raw X, Y, and Z magnetic data and temperature data) are accessible through the I2C interface.
This Click board™ can be configured to various power options, including Wake-Up and Sleep mode, optimizing system power consumption. Also, an integrated angle calculation engine (CORDIC) provides complete 360° angular position information for both on-axis and off-axis angle measurement topologies, performed via two user-selected magnetic axes. It also features magnetic gain and offset correction to mitigate the impact of system mechanical error sources.
3D Hall 11 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz to enable any combination of magnetic axes and temperature measurements. Besides a dedicated interrupt pin, the INT pin of the mikroBUS™ socket act as a system interrupt during low power Wake-Up and Sleep mode and can also be used by an MCU to trigger a new sensor conversion.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VIO SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
