La carte s'installe avec quelques précautions pour le courant électrostatique sur les pins 15-26 du RPi3.
(Pas de souci pour ce qui est branché sur 6-8-10).
Une fois bien vérifié que le fichier /boot/config.txt contienne bien ces 2 lignes :
dtparam=spi=on dtoverlay=at86rf233
la commande ``sudo modprobe at86rf230 `` doit charger le bon module.
