A quick question on a topic I could not find answered anywhere else.

Aside from the USB-b connector on the back of the Typhoon, there are 3 others.
1/. 4 pin fan connector
2/. 2x USB headers
Assuming i am correct on these, i would really like to know what the pin assignments are on the two USB headers and are there any limitations to what can be connected to these headers?
Thanx

The 2x5 pin blocks are two GX Expantion connectors that allow you to plug in additional controller boards such as Fan Controller boards and GPO Boards. These boards are not for sale yet but they are comming.

Left of the mini-B connector is a 4 pin power connector to supply additional power for high powered Add-on boards.

Right of the mini-b connector is a 4 pin alternative usb connector, we only populate this on request for larger oem customers who do not wish to use the mini-B connector.
