The 7Semi HMC6343 module is a fully integrated 3-axis electronic compass with advanced tilt compensation and heading algorithms. Based on Honeywell’s highly sensitive AMR (Anisotropic Magneto-Resistive) technology, it combines magnetometers, accelerometers, and an onboard microcontroller to provide heading, pitch, and roll data. Perfect for robotics, navigation systems, and drone orientation, this compact sensor delivers accurate directional measurements even in dynamic environments.

This module offers I2C communication for easy integration with Arduino, Raspberry Pi, STM32, ESP32, and other microcontrollers.
