Board interface connectors
This chapter provides a useful cross reference to see the connection from the motherboard to the board interface
connector, and what MCU pins are connected to the interface connector on the daughter cards.
The
Table 7. Ethernet control jumpers
lists all the connections to the board interface connector on both
motherboard and daughter cards. The table on the left lists the 240 connections for the first interface connector
(J43), the table on the right lists the 240 connections for the second interface connector (J56): the column
‘Motherboard’ shows the motherboard connections to the interface connectors like power supply connections and
user area port pins.
Ground signals are not listed here. A solid ground connection is achieved through the middle bar of the interface
connector.
