Introduction
Most of the information was based on the top and bottom layers of a dechipped 360
motherboard and decapped chips, I will update the information once I gain full knowledge
of the inner layers of the motherboard.
For reference, I have also included some information I have gathered from images of
Development Hardware and XDK hardware found on the net.
Please double-check my information, I am human and I do make mistakes. I have also
attempted to give credit where credit was due. If you find any errors or omissions, please
let me know so that I can correct it on future versions.
Like most, I am doing this as a hobby in my spare time, so I will do my best to keep the
information up to date but I can not make any guarantees.
I am currently looking for a supplier/manufacturer for the following components;
Controller Headset Port
Both the Male and Female
Connector.
Memory Card Port
Male Connector
(On Memory Card)
RF Module Port
Male Connector
(On RF Module)
Hard Drive Port
Male Connector
(On Hard Drive)
My current employment position will be changing in the near future, so I will be open for new
opportunities. I am a Canadian citizen living in Waterloo, ON, Canada with a background in
Electronics Engineering and Management. Feel free to contact me for more details.

Note:
Pin 7 Turns Pins 4, 5, 6 on when it is tied to ground.
Power Supply is difficult to open up. I would not recommend it.
1) Remove rubber feet (they are glued in place). This will probably destroy them.
2) Dig out all the glue, including the glue in the head of the philips screws.
3) Remove the 4 screws.
4) Remove bottom cover.
5) Remove the two philips screws. One on each side of the heat sink.
6) Gently wiggle circuit board out of the top cover. The DC supply side should lift
up first. Heat sink grease is preventing the easy removal of the circuit board.
Continue to wiggle the circuit board until the grease bond is broken.

XDK DC Power
Note:
This connector is used to supply power to the extra circuitry used in the XDK
(motherboard version 009).
The circuitry is located in the "Sidecar" that attaches to the hard drive side of the
xbox 360.
