SparkFun Digital Compass with Integrated Tilt Compensation and Qwiic Interface
The SparkFun Digital Compass – HMC6343 (Qwiic) is a high-accuracy electronic compass module designed for reliable navigation and orientation sensing without the complexity typically associated with raw magnetometers. By combining 3-axis magneto-resistive sensors, accelerometers, and an onboard microprocessor into a single factory-calibrated package, this module delivers stable heading and tilt data straight out of the box. This makes it especially suitable for robotics, UAVs, autonomous vehicles, handheld navigation devices, and academic projects where dependable directional information is essential.
Enhanced with SparkFun’s solder-free Qwiic ecosystem, the HMC6343 becomes exceptionally easy to integrate into 3.3V I2C-based systems. The onboard EEPROM stores calibration and configuration data, reducing setup time and ensuring consistent performance across power cycles. With low current consumption and compact design, this digital compass is well suited for both portable and embedded applications requiring professional-grade navigation accuracy.
Key Features:
- Fully Integrated Compass Module: Combines 3-axis MR sensors, accelerometers, and MCU in one package
- Reliable Heading Output: Provides stable compass heading with tilt compensation
- Factory Calibrated: Minimises user calibration effort compared to discrete magnetometers
- Qwiic Connectivity: Dual Qwiic connectors for quick, solder-free I2C integration
