D'autres pistes à creuser :

  * Pas certain que le Rpi soit en cause pour ce cas. A voir pour tester une autre carte arduino → Chip CH340G foireux?
  * Voir si mon relais de plateau ne balance pas trop de cochonneries (à mesurer donc et mettre un Snubber pour corriger si nécessaire) : [[https://youtu.be/fVuKh_1dVkU|Cyrob - Snubber ]]

<WRAP center round tip 90%> \\
Suite au remplacement par un arduino officiel : plus de soucis. Fort probable que le CH340G soit une merguez. \\
