    16-bit 48KHz I2S USB audio
    HID control
    Single sided board (for DIY)
    Same footprint as the V5/V7
    Simplified for DIY
    Bootloader for firmware upgrade
    Support V5/V7/Verona via adaptor
    Slave/SERMMI firmware

    Centrafuse plugin is basically done.
    Yes I do have a real prototype right here on my desk.

    Home made PCB with some modification, test points and programmer attatched and wire antenna.

    DAB module hidden at the bottom. The 2x15 socket is there for testing. Module should be soldered directly to the board to reduce the size of the whole unit by 1cm or so.

    It appears as audio device and HID. Although as a COM can also work but I dont like the idea of having to select the port and using a driver, windows take cares of it all.

    Ignore the "FM Radio", that one is the Silab USB radio.

    If anyone is still interested in DIY Ill post the pinout detail.

    Thx had a look at the website and it looks alot smaller than the v5/v7

    About 30-40% smaller. It still uses the 0.1in pitch connector, soldering shouldnt be a problem. They only come with master firmware so you will need to flash it with the correct one. The programming is via the 0.1in connector, it is much easier unlike the V5/V7 where you will need to solder wires on those close pads.

    This looks very interesting. Do you have any plans to sell the boards with chips mounted. I really hate to solder SMD components myself.

    Today I use the Craig Brass module with the Venice 7 slave module but I do not like the extra DA/AD convertion introduced by this setup. I would much rather get I2S directly to the computer and do the sound conversion in the processor. I use the new Alpine PXA H800 processor which I feed by optical cable from carputer. I control the processor by Alpine RUX-C800 remote commander(This is not needed however I like to have a volume knob) The sound is very good except with my DAB radio which is only ok at the best.

    Some firmware for the venice has SPDIF support. It would be just a matter of adding an SPDIF TX module and it should work in theory.

    I dont think I have plan to sell it. Ill probably make a few for people I know very well. I could post the "how-to" guide but that probably wont happen for various reason.

    Has anyone intergrated this into RR?

    Is this going to be the best option for FM radio in the UK with a carputer?

    V5 inRR

    I have just come back to this thread after some time. Apparently I am one of only a few to be using V5 in RR. I guess I was lucky to get my module after just 3 weeks from C.B.
    I changed the module to V5, I am a complete novice to this but managed the following skin.

    I have been using this every day for months now, reception good with Kinetic roof aerial very rare breakup/dropout, well worth the effort.
    Grey blank at bottom give station details following freq up/down, select selects that station.
    Presets selected by touching station name, highlighted station playing (caught this one scrolling)
    Blank blue buttons are page up/down (icon only shows when button active).
    If I did it again I would not bother with some if the information, and would make the preset editing buttons smaller, as you do not use them on the move.
    I have the V7 from C.B. somewhere, was going to offer it for sale, but cant find it, I will keep looking.
