assembled to serve as a prototype board Final board will be produced on MTU’s

milling machine XB interfaces with EVB through P6 and P8

connectors

Project DefinitionProject Definition

The purpose of this project is to design an expansion board for the Motorola 505EVB which will allow students to interface external circuits, generate interrupt signals to the CPU, and protect the EVB from accidental damage by the user.
