3D Hall 10 Click is a compact add-on board used to detect the strength of a magnetic field in all three dimensions. This board features the TMAG5170, a high-precision linear 3D Hall effect sensor from Texas Instruments. The TMAG5170 features an SPI interface for configuration by MCU. The measurement data is provided in digital format of 12-bits corresponding to the magnetic field measured in each X, Y, and Z axes. It can achieve ultra-high precision at speeds up to 20kSPS for faster and more accurate real-time control and offers multiple diagnostics features to detect and report both system and device-level failures. This Click board™ is designed for a wide range of industrial and personal electronics applications.

3D Hall 10 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

3D Hall 10 Click as its foundation uses the TMAG5170, 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 from ±25mT to ±100mT from Texas Instruments. The high level of integration offers flexibility and accuracy in various industrial and personal electronics applications such as position sensing systems. A precision 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.

An integrated angle calculation engine (CORDIC) is performed using two user-selected magnetic axes and provides complete 360° angular position information for both on- and off-axis angle measurement topologies. The device also features magnetic gain and offset correction to mitigate the impact of system mechanical error sources.

3D Hall 10 Click communicates with MCU through a register-selectable standard SPI interface that enables high clock speed up to 10MHz to enable any combination of magnetic axes and temperature measurements. The SPI communication features a user-enabled cyclic redundancy check to enhance the data integrity. A dedicated alert pin marked as ALR and routed on the INT pin of the mikroBUS™ socket can act as a system interrupt during low power Wake-up and Sleep mode and be used by an MCU to trigger a new sensor conversion. Besides, the TMAG5170 offers multiple diagnostics features to detect and report both system and device-level failures.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC 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 containing easy-to-use functions and an example code that can be used, as a reference, for further development.
