Thanks for fast reply appreciate it. maybe this is too much to ask, just to make sure. can the VGT replace the VET one without any problem? from your reply before i see the only difference is only on the flash memory and both are have same capabilities on anything else. i'm working on a project and i'm told to buy exactly that, VET one that is. but as i can't find it i want to replace it with the VGT one? are it's okay? and won't have any problem to interchange between both? so much thanks

There is no differences except the Flash memory size.

Since VGT has more Flash than VET, VGT can replace VET without any issue.

No need for additional software. So go ahead.

Just to be sure: I need to check internally about that U. It could be something related to licensing or something like that.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
