Hello,   http://primtux.fr/ is a debian configuration for french schools. I'm trying to participate to make a dynamic in order to deploy PrimTux on open hardware nano computer in schools, to support makers activities for 6 years old to 10 years old (3D printing, Snap!, OpenScad, arduino IDE...).   Choosing the right card is a big problem for a newbie as me. I have benchmarked some cards https://mutualiser-les-comparatifs.les-cercles-vertueux.org/comparatif-des-nano-ordinateur
