Spectacle Inertia Board
DEV-13992 RoHS Open Source Hardware
Description: The Spectacle Inertia Board makes it easy to sense motion or orientation with a
Spectacle project. The Spectacle Inertia Board is designed to allow your Spectacle to detect whether
it is moving or stationary, or whether it is under acceleration. At the heart of each Inertia Board is the
trustworthy ADXL345 triple-axis MEMS accelerometer. The ADXL345 is a perfect fit for your
Spectacle project when it comes to all things Inertia!
The Inertia Board is equipped with two 3.5mm TRRS jacks for Spectacle control signals from a
Director Board. The one labeled “In” should be plugged into a board that is closer to the Director
Board than the Inertia Board is, or into the Director Board itself. Make sure to pay attention to the
directionality of the jacks, as they will dictate how your Spectacle modules speak with one another
and with the Director Board. As with every other Spectacle module, you will need the Director Board
to operate any Spectacle project.
We have written an in-depth User’s Guide and Inertia Board Hookup Guide to help direct you
through each step of setting up this and any board in the Spectacle product line. You will be
surprised by how easy and quick it is to make yourself into a Spectacle!
