Okeydokes... I'll give this a stab.
First, the SMiRF, which I'm quite familiar with.
Here's how the connections go:
I'm not familiar with the Nova's board, so the actual pins that you're hooking up to are probably going to be named a bit differently.
Someone on these forums just got his radio hooked up to his RN-1, so he'll be able to point out where these pins are for ya.
Well, the SMiFF has standard .1" spaced male pins sticking out of it, just like the Robonova's board has.
But, because their both male, you'll need a female connector on each end of a jumper wire to attach them (at least, that's one way to do it).
I'm familiar with www.jameco.com
, so I'll tell you the part numbers from there that I'm familiar with.
Once you go there and see what it is, you shouldn't have problems finding them on a site that you prefer.
First, you get a wire (I'd recommend 24AWG or thicker wire, for sensors).
Then you crimp one of these buggers (100765) onto each end (this crimper works with those crimps: 99443) .
Repeat that process for every pin that you have to hook together.
Once completed, cut of a section of these female housings (103157) and stick the crimped ends into them.
Now you're ready to plug and play.
Hmm... that's an interesting screen there.
Well, a brief look shows that it's made to interface with an ARM (a relatively new, very high-end set of microcontrollers).
I'm afraid that I don't know how those buggers work.
Off the top of my head, I sort of doubt that the RN-1's micro can handle that kind of processing.
If you're willing to invest in a seperate microcontroller, then the screen is a possibility.
By the way, the connector for that screen is linked to on the page (it's a digikey.com part).
The range sensor is definitely within the RN-1's capabilities.
I'm not familiar with that exact model, but it says to just take off the back casing and solder wires directly to it.
The reason for this is that it has an odd Japanese coupling that would be hard for you to find.
If you hunt around the forums, I'm sure someone's already implemented a rangefinder on their RN-1 and can walk you through it.
