Based on an Altair chipset, the Skywire 4G LTE Cat 1 embedded modem, and its Skywire Verizon companion model are the first Cat 1 LTE modems with FCC and carrier-required end-device-certification. End-device-certification eliminates months of testing and tens of thousands of dollars in cost and helps speed products to market.
Like other modems in the NimbeLink's Skywire family, this new LTE Cat 1 modem is the smallest in the industry and is compatible with a variety of NimbeLink development kits and microprocessor shields, for fast, easy integration of cellular connectivity into new and existing products. It also shares the Digi's Xbee® Standard interface with all other modems in the Skywire family, ensuring long product life. Its U.FL port provides antenna flexibility, and the modem requires just voltage and a UART or USB connection. It supports a wide range of voltages for design flexibility.
