3.1 Main board mechanical properties
The HDK8450 Main Board measuring 100 mm x 85 mm is where all the processing occurs. It is
connected to the Expansion Card via two 60 pin high speed, and one 40 pin low speed board-to-
board connectors. The purpose of the connectors is to bring out essential signals so that other
peripherals can interface with the platform.
