-- verifier les tailles de police sur le pcb
+- DRC avec config seedstudio
+- executer script change-font.scr
+- verifier l'emplacement + tailles de police sur le pcb
 - plan de masse
 - http://www.atmel.com/Images/Atmel-2521-AVR-Hardware-Design-Considerations_Application-Note_AVR042.pdf
+- les écritures peuvent etre placées sur des pistes, mais pas des pads, des 2 cotés
+- texte indiquant la version de la carte sur le PCB
+- points de tests (GND au moins)
+- pour générer les gerber, utiliser un fichier .cam fourni par seedstudio
+  (ex: Seeed_Gerber_Generater_2-layer.cam)
+  vérifier que bValues et tValues sont bien aussi dans les layers qui vont bien
+  (ce n'est pas le cas sur le fichier seeedstudio par defaut)
