Embedded modem integrates HSPA/GSM connectivity

Mouser Electronics is now stocking the Digi XBee Cellular 3G global embedded modem. Designed to help original equipment manufacturers (OEMs) avoid time-consuming and expensive FCC and PTCRB end-device certifications, the modem enables engineers to quickly and easily integrate 3G (HSPA/GSM) with 2G fallback connectivity into their machine-to-machine (M2M) and Internet of Things (IoT) designs.

The Digi XBee Cellular 3G global embedded modem, available from Mouser Electronics, operates at 2.7 to 5.5 V supply voltage and offers low-power listening and deep-sleep modes optimized for battery-powered applications. The modem utilizes 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 for added manageability and convenience.

The programmable modem supports custom MicroPython applications running directly onboard, which allows users to more efficiently manage their devices and 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 customers can simply drop this modem into their existing designs to instantly achieve 3G cellular integration, without the difficulty of a complete re-design.

All Digi XBee products share the same footprint and software interface, so the Digi XBee Cellular modems offer a cost-effective, longer-range solution with a standardized footprint that allows designers to easily upgrade to new technologies. Customers can seamlessly transition from existing Digi XBee modems to this new modem 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 is also offering 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. The Digi XBee Cellular embedded modems are ideal for remote equipment control, environmental monitoring, intelligent lighting systems, digital signage, and oil and gas sensors.
