Introduction

The HMC6343 is a solid-state compass module with tilt compensation from Honeywell. The HMC6343 has three axis of magneto, three axis of accelerometer, and a PIC core running all the calculations. What you get is a compass heading over I2C that stays the same even as you tilt the board. Solid-state (and many classic water based) compasses fail badly when not held flat. The tilt compensated HMC6343 is crucial for those real-world compass applications. Who says robots have to stay flat?

• I2C interface
• 2 degree heading accuracy
