Freescale On WaRP
To build wearable tech, manufacturers face restrictions on power, connectivity, size, usability and myriad other factors. Addressing some of these needs is the wearable reference platform, an open-source project for running Android. Freescale is a major contributor to the project, and the Motorola spinoff was on hand to demonstrate several real-world implementations of the platform that are already in production. The WaRPboard combines a Cortex A9 ARM-based Freescale processor with a daughtercard option for deploying peripherals based on need. "We use a daughtercard with a microcontroller to handle wireless charging and a sensor hub, and frees up the main processor for other tasks," said Sujata Neidig, Freescale's business development manager.
