Recently bought the v3.5 bridge, and currently I'm testing it a little.
I want to use the bridge, to connect serveral NMEA devices with Raymarine ST40 displays.
I managed to connect an Autonic NMEA wind masthead unit with the ST40 wind display using the gadgetpool bridge.
Later I will also connect an VDO logspeed/paddlewheel, and VDO depthsounder, using an Actisens DST-2 unit to convert the signal to NMEA 0183, and I will connect an Evermore SA-920 GPS unit.
I have the ST40 depth / speed / compass / 2x wind display's mounted on a removable dashboard, and the only thing feeding this dashboard is the seatalkcable, just unplug it, and the whole dashboard can be dismounted.
First I tried to use a Raymarine E85001 for this purpose, but this thing was rubbish, the buildquality was really bad and the functions very limited. The charm of the gadgetpools bridge is the function to use GPS course to feed the ST40 compass display, and to use GPS speed to feed the ST40 speed display, this means you do not have to buy or install a fluxgate compass neither a paddlewheel.
So far all seems to work fine in my test setup, I just have to mount it to the actual boat.
I will place pictures when everything is fitted and working. ( before august 2013 )

thanks for your report - and thanks for the tip with the wind unit.
Meanwhile I also got one and will test it.
If you should have a report or any pictures for our users - would be great.
Just been sailing for 3 weeks, using the bridge and the ST40 displays.
Everything works great.
I promised some pictures, but forgot to make some of the installed bridge, will do that very soon.
Here is de working set of displays, LOGspeed is actually the GPS speed, and heading is actually the GPS heading, true wind is also shown correct, al thanks to the bridge.
I Use a shipmodule multiplexer, which makes it easy to sent NMEA / commands to the bridge, but I see the new gadgetpool bridge has a USB port and software comming with it, which is awesome !.
the working displays :
I use a standard 3 string 1,5 mm2 cable and weipu SP13 IP68 connectors to feed the displays, the console/dashboard can be removed very fast and easy. ( the woodwork is not the final console, just a fast setup for the holliday )
