A quoi correspondent les points de test au dos des Raspberry Pi ???
Utiliser durant les contrôles lors de la fabrication, il peuvent servir pour un projet où un hack !
Il n’existe pas de documentation explicite sur le détails des points de tests ainsi les informations ci-dessous sont issues de recherches sur le web et centralisées sur ce blog.
Je vais essayer de maintenir à jour les listes, cependant je ne peux pas garantir l’exactitude de ces informations. Il est donc conseillé de vérifier que le signal correspond à ce que vous attendez avant de l’utiliser !
