Thank you for posting this poll.
As of now the only thing we have broken is 1 Analog breakout by wiring the PD with reversed polarity (luckily everything else is polarity protected). It is also lucky for the student I never found out who it was

I will be watching this thread closely to see what kind of failures teams are experiencing. The DS in particular appears to be plagued with a variety of problems. It is very worrying to see a respected, thorough team such as 25 posting comments such as the one Wayne has posted here.
