There are 6 other Overo COMs with more features selling between 149 and 219 USD per unit called Air, Fire, Tide, Water, FE and Earth. Extra features include things like Bluetooth, Wifi, a DSP and OpenGL support.

Gumstix Overo COM are supplied with Linux 2.6.34 and use OpenEmbedded development environment.

For software development on the Overo platform, you can visit Gumstix Developer Website to get started and more specifically visit the Software Development How-Tos, download the pre-built images and learn how to build the Overo linux images with OpenEmbedded. You can also join gumstix-users mailing list.

You can also get details on Overo COMs Hardware such as details on the connection boards, the schematics, PCB layouts, etc…

Gumstix Overo boards could be considered as an alternative to Beagleboard for software development as they are also build around TI OMAP3 processors. However, they seem slightly pricer for the same features and there is currently not a large community as is the case with the Beagleboard.
