The u-blox C027 application board is an out-of-the-box rapid prototyping solution for IoT applications that support GSM, UMTS and CDMA networks. The application board has a MAX-M8Q GPS/GNSS receiver and a LISA UMTS/CDMA or SARA GSM cellular module, enabling straightforward development of location-aware, global communicating applications. To make development even easier, the C027 is supported by the powerful and flexible open-source Arm Mbed development platform (mbed.org/platforms/u-blox-C027) which provides free software libraries, hardware designs and online tools for professional and rapid prototyping. The platform gives access to a high-level standards-based C/C++ SDK for developing applications on the u-blox C027, a large component database of drivers for peripheral components that can be connected to it, and online compiler and developer tools for efficient reuse and collaboration on designs to create products quickly.
