      Does anyone know if the LTE-M1: Bluetooth, Cellular 4G LTE CAT-M1 (AT&T/Verizon) is still available from Digi XBee Cellular? When I do a search for it on their site this comes up Digi XBee Cellular LTE Cat 1, Verizon LTE Cat 1, Dual U.FL, TH.

       

      Thanks

      Yes, Digi-Key has over 4,500 of them in stock right now:  https://www.digikey.com/en/products/detail/digi/XB3-C-A2-UT-001/7932027

      Mouser only has ~350 right now and is slightly more expensive than Digi-Key, so that’s why we recommend Digi-Key.

      Note that Digi (makers of the cellular modem) and Digi-Key (an electronics distributor) have very similar names, but are completely unrelated.

      Another question now that I have this part it specifically says not to open it “except at a static free workstation”.  Will a concrete floor and a discharge prior to opening the bag work?

      All bare-board electronics such as the Digi LTE cellular board and the EnviroDIY Mayfly are sensitive to static electricity and theoretically they could be damaged if you aren’t careful.  That said, the Mayfly is pretty hardy and I haven’t experienced any problems after handling multiple thousands of boards over the last few years in all sorts of environments.  However, the LTE module is more sensitive because of its exposed pins and more-sensitive electronics.  You shouldn’t put it in your pocket or carry it around in your hand while walking around, especially on carpet in low-humidity environments.  But you should be safe to remove it from the package and examine it if you’re careful, and you can connect it to the Mayfly board (using the LTEBee adapter board) at any time.  Just be careful that you don’t damage the small header pins since they are easy to bend, especially when removing the Bee module from the adapter board.

      Another thing to note, we usually ship most of the items EnviroDIY makes (like the Mayfly, the LTEBee adapter, and other accessories) inside a foil bag that has a “static sensitive” warning on it.  Those are just the default bags that the manufacturer uses, and isn’t an actual warning.  Just be careful with the boards like you would any sensitive electronic device:  avoid moisture and physical damage.
