Overo® Earth COM
OMAP3503-based Gumstix Overo® computer-on-module
NOTE - Gumstix has increased the flash memory to 1 GB on the Overo® Earth COM series (Revision 3951). Some customers using custom images may need to update their MLO/UBoot.
Our entry-level Overo® computer-on-module with 512 MB of RAM and 512 MB of onboard NAND flash memory, the versatile Overo® Earth COM is perfect for designs without the need for wireless communications.
We recommend considering the AM3730-based Overo® EarthSTORM COM; The Overo® Earth is intended only for users who specifically require the Texas Instruments OMAP3503 applications processor in their design.
