TurtleCore is an expansion board for any Overo COM. It can be snapped into the cargo bay of an iRobot Create® so that engineers and makers can use Linux in prototyping their iRobot Create.

The TurtleCore™ expansion board sits in the cargo bay of the original (Version 1) iRobot Create® Programmable Robot, drawing power over the DB25 connector to power an Overo® COM or Overo STORM series of COMs. Using the COM on the TurtleCore means Linux tools are available, including ROS, for high level programming.

There are 3 USB ports and several male-header pins available with GPIO access, as well as standoffs and screws to support the TurtleCore in the Create cargo bay.

For more information on getting started with the TurtleCore Expansion Board, visit the Gumstix Developer Center.
