Features
- Sensitive to microtesla (µT) variations in magnetic field strength.
- Simplifies direction by resolving magnetic field measurements into two components axes.
- 6-bit (64-direction) resolution after calibration
- Only 30 to 40 ms between start measurement and data-ready with simple synchronous serial interface.
- Built-in resistor protection for data pins eliminates bus conflict risks.
- Compact and breadboard-friendly 0.3 inch, 6-pin DIP package.
- Arduino Compatible.
