The memory chip on that unit is operated outside it's specifications, which you can download here:

A 3.3V part, which is not specified to be 5V tolerant, will fail sooner or later. I do proper designs that stand the test of time, not such tinkering as the board you're referring to here.

Once again, stop the discussion. I know you're not a customer for the ACA500. If you want a custom design, I'm willing to negotiate a contract.
