XB3 Cellular LTE CAT 1 AT&T version obsolete?

In the user manual for the XB3 cellular development kit it says “Telit LE866A1-NA (AT&T, not recommended for new designs)”

The AT&T version is no longer listed in the available part number section on the XB3 LTE Cat 1 module product page.

DigiKey still has some in stock, marked as obsolete.

Does this mean there will be no more AT&T LTE Cat 1 modules, or is an update in the works?


Digi has to discontinue this product due to EOL of Telit cellular modem that it incorporates. A new module supporting AT&T is in making but it will take a while before its available.

In the meantime, you may consider looking at Verizon version of this module.

Of course Verizon may not be available in all locations. We also have the option of CAT-M or NBIOT depending on the location but as I understand it not every tower has this feature and it is more common in areas that are converting to 5G.

Also to consider, supposedly CAT M has better range.

My potential application has a lot of rural locations, hard to tell what kind of success we will have with the available technologies and carriers without doing a lot of site surveys.

Let me know when there is a Starlink module.
