The LPC2478 OEM Board has SODIMM format and is only 66x48 mm. All processor signals are available on the 200 pos connector for easy expansion.

The board can be used in OEM applications, as well as for education purposes, experiment, and prototype projects. Use the LPC2478 Developer´s Kit to get up-and-running quickly with the board.

The OEM Board is also perfect for running uClinux with its large on-board RAM and Flash, network and graphics capabilities.

Low Cost

The LPC2478 OEM Board is low cost and can be used for prototyping/development as well as for OEM production. Modifications for OEM applications can easily be done for volume customers. Contact Embedded Artists for further information about design and production services.
