Do you know if this could be a replacement for the unit Range Video Sells here:

I suspect the Rangeview module is plain NMEA. That's fine for OSD, but not best for UAV use. You'd need to reprogram ours to NMEA mode to use with the Rangevideo OSDs.

And ours have rechargable coin battery....

how well this gps support RFI ? because i have the same one from flytron, with simpleosd xl and it get messed by the most tiny RFI from DC/DC reg of camera, or any other noise source

"Note that the new MediaTek has custom and exclusive "DIYDrones" firmware that allows the unit to output an efficient and very compressed binary protocol."

Jordi, where can we find the documentation on the "custom and exclusive" binary protocol? Since it was mask programmed exclusively for DIYDrones, and you're selling it (as well as the MT3329 without the board), then I imagine you'd already have the documentation for the binary protocol. Please post a link to it... the link in the store is just to the "standard" version.

How did you get the manufacturer to crank out "customized for DIYDrones" versions of their firmware, without committing to huge (100,000+) quantities? Also, in order for the manufacturer to customize it, you must have given them some specs as to what you wanted the binary protocol to look like. In other words, if it was customized to your specifications, then by definition you already have those specifications. Could you post them (the binary protocol), please?

Or is there more to this than meets the eye?

Is it possible to program and existing Media Tek with the "custom and exclusive" binary protocol?

Will the adapter board be sold seperately?

Where is coin battery?

Nice job Guys! That was really quick.

Regards Wallace

"We like this one a lot. It's nearly as good as the uBlox module, but cheaper and smaller."

Chris - What is the factual basis for your claim? The Sparkfun tests (as opposed to subjective opinion or just plain conjecture) clearly show that the older MediaTek MT3318 with a passive antenna outperforms the U-Blox even with an active antenna. What is the basis for your claim?

Also, what is your definition of "nearly as good?" I have difficulty following flowery generalizations using vague and ambiguous terms, especially when claims are being made that go against the grain of formal tests.

Lew, personal experience. Sorry you don't like my chatty blog posts. I'll try to write only in precision scientific language going forward, just to make you happier.

I ordered this from the store last night. Now, I'm looking at it again...do I need an adapter cable with the jst plugs to connect it to the ArduPilot Mega/Oil Pan, or does it solder on?
