Armonie

Armonie is a minimalist processor board. Based on an ARM Intel XScale, It is designed with three differents uses in the mind. Like RokEPXA it is suitable for the Cyclope robot. It also fits well for an embedded multimedia system, in conjuction with the eMediaKit multimedia extension board. It's relative simplicity and accessibility makes it ideal for education use, here at LAP for the embedded system lecture.
