The picture sequence below shows how we were able to intagrate a USB DAB receiver into the back of an openmoko FreeRunner. The nice thing about the proposed approach is that the "internal" USB receiver can be powered by the internal battery while the usual external USB power supply can also be used to recharge the battery .

It all starts with an new FreeRunner that you have to "break" to access the USB test points
All packaging has to be removed to reach the four USB test points. Test points can be seen just on the left of the external USB connector. Note that in order to reach them, a module that connects on top of them has to be removed.
We see here the soldered red wire which is the +5v. It is a good time to note that the NEO 1973 does not have the circuitry to feed external USB devices with its own battery while the FreeRunner can.
The four USB wires are connected and module put back in place on top of them.
We wanted to create room to fit a USB key type receiver and its antenna inside a well integrated prototype. We used the CAD drawings released by FIC to create and 3D print our "spacer".
The other side. We were amazed to see what can be done with 3D printing as we discovered it. These pieces are not perfect but it's just great for rapid prototyping.
Putting everything back into place.
USB wires coming out close form the SIM card.
The back cover of the FreeRunner is clipped into our spacer. The DAB USB receiver connects to the motherboard. Mini USB connectors are used and can fit beside battery when DAB module is not used.
A comparison of our "thick" prototypes and a regular FreeRunner
It had to look good. We designed a skin with project name and CRC logo with typical canadian scenery.
