Architecture / Goals /

• What are we looking for ?

– Fast prototyping for this « proof of concept » project. – An all‐in‐one GPS/GPRS/DSP solution – Light‐weight – Low‐power – Flexibility

• Easily interface with all kinds of sensors (analog, digital, …)
• Evolutivity

– Embedded intelligence on‐board for power management and other projects.
