Summary

Initially developed as research platform for the EYES project Targets the low-power end of the WSN application spectra Shows how the cost of the WSN platforms can be reduced by

reusing designs from related high volume markets TDA 5250 family originally developed for the “Remote key-less car

entry” application Node design influenced by Infineon’s wireless tire pressure

measurement solutions

eyesIFXv2 motes (868MHz) commercially available in Q2/05, after the end of the EYES project
