Gumstix Overo and Tobiwo 27950 GS3503T-R2889

The typical Gumstix configuration consists of a computer-on-module or COM and an expansion board.

• The expansion board can be off-the-shelf from Gumstix or custom made. Gumstix openly publishes the schematics of all off-the-shelf expansion boards to assist rapid development of custom solutions.
• For some applications, a camera board can be connected to the top of the Overo COM via a ribbon cable.
• A typical Verdex Pro assembly consists of a Verdex Pro COM sandwiched between a 60-pin expansion board and an 80-pin expansion board.

The DuoVero COM, Overo COM and Verdex Pro COMs are unique to Gumstix.

The following information addresses the most common expansion options: a DuoVero COM with Parlor expansion board, an Overo COM mounted on a Tobi expansion board, and a Verdex Pro COM mounted on a Console-VX expansion board.

Overo and Tobi

An Overo COM connects to an Overo series expansion board via the two 70-pin AVX connectors located on the bottom side of the COM. Place the Tobi board on a flat, static-safe surface, align the COM with the white outline on the board above the connectors and gently press on the COM until it clicks into place.
