Development kit merges GPS, MCU and cellular modem for location-aware projects

October 29, 2013 // By Julien Happich
u‑blox and ARM have jointly released a flexible and easy-to-use prototyping kit for designing wirelessly connected, location-aware internet devices: the ARM mbed-enabled u‑blox C027 Internet-of-Things (IoT) starter kit.

The C027 delivers out-of-the-box wireless internet connectivity based on a compact u-blox 2G, 3G or CDMA cellular modem plus global positioning module. Together with the ARM Cortex-M3 32-bit processor and access to all the resources of the ARM mbed project, the kit enables developers to quickly move prototypes of intelligent ARM-based technology into production-ready designs.

The C027 kit measures 54 x 98mm, it contains a u-blox “ SARA” GSM or “ LISA” UMTS/CDMA cellular modem, a “ MAX” GPS/GNSS positioning module, and an ARM 32-bit Cortex-M3 microcontroller with 512k of Flash Memory and 64kB RAM, user-programmable via USB. CAN bus and Ethernet interfaces are provided. The board also provides direct connector with 22 GPIOs to access components via I 2C, SPI, UART, and I 2S digital audio. The hardware is supported by the open-source ARM mbed development platform ( which provides free software libraries, hardware designs and online tools for professional and rapid prototyping of ARM-based designs.
