Problema atmega 2560 r3

-

salve tutti! sono nuovo del forum e sto costruendo una stampante reprap con una mega 2560r3 e ho incontrato un po' di ostacoli.
dopo aver installato il driver e aver seguito tutta la procedura primi caricamenti sono andati buon fine, ma poi la scheda ha cominciato scaldare attorno al chip dell'usb-ttl e il led l giallo rimane sempre acceso. il pc non riconosce più la scheda e mi dice che nella com non c'è nulla. ho provato il reset ma non cambia nulla.
qualcuno ha già riscontrato questo problema? come posso capire se è saltato il modulo usb ttl?
la garanzia in questo caso può essere ancora valida? grazie mille dell'appoggio!

benvenuto.  :)
