HSPA/GSM connectivity via 3G global embedded modems, in distribution
The embedded modem operates at 2.7 to 5.5V supply voltage and offers low-power listening and deep-sleep modes optimized for battery-powered applications. The modem uses Digi’s TrustFence security framework, which includes Secure Boot, encrypted security keys, secure JTAG, and SSL/TLS 1.2 cryptographic protocols. All security and feature updates are performed using over-the-air (OTA) firmware.
The programmable modem supports custom MicroPython applications running directly onboard, which can eliminate the need for an external microcontroller. The device includes the full suite of standard Digi XBee API frames and AT commands, so existing users of earlier versions can drop this modem into their existing designs to instantly achieve 3G cellular integration. All Digi XBee products share the same footprint and software interface. Transition from existing Digi XBee modems to this new modem is posible with only minor software adjustments, configuring and editing data either locally through Digi’s XCTU software or remotely using the Digi Remote Manager interface.
Mouser also has the Digi XBee Cellular 3G global development kit, which includes the embedded modem, development board, an activated SIM card, and six months of free cellular data service to allow for immediate development.
