LPC2478 Developers Kit (32 bit bus) Embedded Artists

DESCRIPTION

RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.

The LPC2478 Developer’s Kit is a ready to use platform that will let you explore the many features of the LPC247x microcontroller series in general and the LPC2478 in particular.

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

Focus on your value-added application by using this Developer’s Kit as your prototyping platform. It includes the software components needed to get up-and-running with your software development on day 1.

When you are finished with prototyping and/or evaluation you can easily transfer your application and the OEM Board into production.

The LPC2478 OEM Board is very 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.
