Connector Descriptions
The following sections describe the use of each connector on the I/O Development Board.
J5 — Utility 1
J5, the Utility 1 connector connects to the Little Board/P5x Utility 1 connector (J16). It provides
connections to an on-board speaker, keyboard connector, reset switch, a connector for external -5V
and -12V power supplies, and a power LED.
If you have the Ampro Quick Start Kit, connect a ribbon cable between J5 on the I/O Development
Board and J16 on the Little Board.
If you install the Little Board on the Little Board Development Platform, it is not necessary to
connect Utility 1 signals to the I/O Development Board. The Utility 1 features are already provided
on the Development Platform.
J2 — Mouse
If you connect J1 to J24 on the Little Board, you can use J2 to connect a PS/2 mouse.
J3, J4 — USB
Connectors J3 and J4 provide connection to USB ports 1 and 2 respectively. These are standard
shielded Type A connectors, the kind typically found on a host or hub. For details about the USB
ports, refer to the Little Board/P5x Technical Manual. To use the USB ports, you must connect a
cable from the I/O board’s J1 connector to the Little Board’s J24 connector.
