I keep forgetting about the Telit :-) I prefer the option because it's
smaller (I don't like the idea of filing down plastics to get a larger
module to fit), it's 3G and newer.
Having said that, the Telit does have a UART interface (where the option
appears to be USB only) - so should be easier to fit into our existing
Do we have samples of the telit available for prototypes, or if not
would it be worth investigating getting hold of some at the same time as
the Option option is explored?
Then at least we have a firm fallback.
I get the impression that the calypso isn't going anywhere, so how about
getting started with Telit based schematics while we're waiting to find
out if the Option is a goer or not?
