Sure thing :)

Connect the SDA pin of the compass to the SDA of the i2c interface on EZ-B Connect the SCL pin of the compass to the SCL of the i2c interface on the EZ-B Connect the VCC pin of the compass to the +5 of the i2c interface on the EZ-B Connect the GND pin of the compass to the GND of the i2c interface on the EZ-B

I noticed the compass i2c is a little strange for wire distance. I kept my wires very short (less than 2 inches). If u make the wires longer, you may need additional pull-up resistors.

MovieMaker had used 10k ohm pull-up resistors: https://synthiam.com/Community/Questions/1303&page=2

Hope that helps :)

Hello DJ Thank you very much, do you mean with SDA and SCL (i2c) from the EZ-B the digital Ports D0-D19?

Top left of that picture I believe, the markings should read SCL, SDA, 5V & GND
