We have purchased a lot of NVIDIA TX1s in the past, but on the latest order we received (P/N: 135-0657-000 R1) and have damaged a lot of the boards. It seems that some of the boards that we used to get in the past (P/N: 135-0620-000 R2 ) were more reliable.
Have there been any issues with P/N: 135-0657-000 R1? Does the R1 mean it is Revision 1? We have a few part numbers with R4 that also seem more reliable.
It is hard to explain how the boards were damaged. They work fine for a few days, and suddenly stop working. We have been using these on a new PCB, but the schematics for this new PCB have been working on a few other designs without any issues. For this new PCB, we have two different TX1s on a PCB and they both run off of 12V(with their own independent filtering capacitors). I have run the R2 board on both ports and it works fine, but the R1s seem to stop working after being used on and off for a few days. I am not sure if these are more prone to being damaged by static electricity or are more sensitive in general.
