This is a simple, modular and inexpensive mini-ITX I/O Board for the Vampire 4 Standalone from Apollo Computer.

It allows you to easily mount the Vampire 4 in any mini-ITX case. The Ports for Mouse and Joystick (DB9 and USB) will be redirected to the back. The I/O Board supports also a 5.25" connector to power a harddrive or optical drive (requires 12V or ATX PSU).

Power Supply

To power the Vampire 4 the I/O Board will give you 3 options:

1. using the default USB PSU
2. using a 12V PSU
3. using an ATX PSU

Be aware! Only power your Vampire 4 from 1 of these options!

External 12V PSU

If you want to use an external 12V PSU you will need 2 additional modules which needs to be installed on the I/O Board.
