That's a good looking compass. It uses I2C so the technically inclined should be able to interface it with a Lego NXT brick.

A BS2 can also use the I2C protocol.

Surprisingly, an advanced search on the Forum for I2C just turned up... NO MATCHES. Every now and then that happens for bizarre reasons. I've seen plenty of I2C posts here, but search just ain't cooperating right now.

Nice looking compass.
If I may ask, where did you find the Coupon?
I bought some of Pololu's other boards on Black Friday 2010, very well made.
