Measure the magnetic field in three axes !

This TinyShield features the high performance and low power Honeywell HMC5883L 3-axis compass. The HMC5883L includes state-of-the-art, high-resolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy.

The Compass TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range between 3 – 5V.

You can also use this shield without the TinyDuino – there are 0.1″ spaced holes for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system.
