Hi Attila, The two versions of the -6T I have experience with - LEA-6T-0-001 and LEA-6T-1-000 - have both had a single shield. So, that implies that these are at least 2 steps older than what's out now. The price? They must be getting them at or near single digits USD.

For one thing, they are way too cheap. LEA-6T is still quite expensive when bought from u-blox directly, eventhough it came down from 180eur/pcs to 140eur. The prices these modules are selling are lower than the cheapest price i've ever seen for LEA-6T's, when bought in the 100s. So, either they bought them in swats of 10k or there is something amis... Also, why would anyone use LEA-6T in navigation module? That does not make sense. The power of the LEA-6T is as a timing module, not for navigation. And last, but not least, the pictures seem wrong. All the LEA modules i've seen, had two shield covers, one over the RF part and one over the digital part. Yet these shown in the pictures have only a single shiled. It might be that u-blox decided to use a single shield for them... though it would seem strange to do that to an already launched product that sells in relatively low volumes. Even more so, as I know that u-blox itself warned users of their modules to ensure an electrically quite enviornment around their modules, for maximum performance. So, i would warn people buying those that they might be fakes...
