What do you need to buy to getting started with RoadRunner

The RoadRunner is a component so its main application is to use it as core for customer designed application boards.

We are designing some RoadRunner carrier boards thought for specific applications like LCD terminals, M2M devices, wireless sensors, etc. but right now the fastest way to try this module is to buy the Berta D2 evaluation board available on this site:
